Introduction
Visual Composer is one of the most popular WordPress page builders today. It helps users design websites using simple drag-and-drop tools. Custom layouts can be made without writing any code. For small business owners, bloggers, or designers, it saves time and effort.
However, many users face problems when using Visual Composer. The builder sometimes does not load or work correctly. It may freeze, show a blank screen, or fail to respond. This can happen without warning, even after normal updates. When this happens, it becomes hard to manage or update your website.
Imagine you’re editing a page, and the builder won’t open. Or you click “Edit with Visual Composer,” and nothing happens. This is a challenging position, particularly when you have to make changes quickly. It can hurt your business, delay updates, and cause lost traffic or sales.
These problems are common, but not impossible to fix. You can troubleshoot and solve them if you follow the correct procedures. You can attempt simple fixes without being a developer.
We’ll explain the root causes of these issues in this guide. We’ll also walk you through each step of solving them. This post will be helpful regardless of your level of experience.
You deserve a website that works every time you need it.
Common Signs Visual Composer Is Broken
When Visual Composer stops working, the signs are usually easy to notice. These problems often show up while editing a page or loading the builder. Your builder might be broken if you see any of these.
- Visual Composer Shows a Blank Screen
One common issue is the blank screen error. You click “Edit with Visual Composer,” and the screen turns white. Nothing loads. The page builder interface is missing.
This often happens due to JavaScript errors or plugin conflicts. It can also result from a failed update. In some cases, your hosting settings may block the builder from loading fully.
- Drag and Drop Features Stop Working
Another red flag is when drag and drop doesn’t work. You try to move elements, but they don’t respond. The layout stays the same, even after several clicks.
This issue can be caused by:
- Themes or plugin conflicts
- Broken scripts or outdated browser versions
- Missing Visual Composer updates
- The Builder Freezes or Becomes Unresponsive
It’s also possible that the constructor loads and then freezes. You can’t click, scroll, or edit anything. This is a sign that Visual Composer editing is broken.
In many cases, this happens after a plugin update or a server error. If not fixed, you may lose access to your page layouts entirely.
- Page Elements Don’t Load at All
Sometimes, only parts of the editor load. There are no buttons, layout blocks, or templates. This is another sign that something is wrong with the builder.
When you notice these signs, it’s time to start troubleshooting.
Why Visual Composer Fails — Common Root Causes
There is typically a very obvious cause when Visual Composer stops functioning. The first step in solving the issue is figuring out what’s causing it. Below are the most common reasons your Visual Composer builder may fail.
- Plugin or Theme Conflicts
One of the top causes of Visual Composer issues is plugin conflicts. WordPress sites often use many plugins. Some of them don’t work well with Visual Composer.
A new plugin you install may break the builder. Even old plugins can cause trouble if they’re outdated or poorly coded. Themes can also create conflicts. Issues could arise if your theme is not completely compatible with Visual Composer.
You might notice that your builder stops loading after a recent install or update. This is usually a sign of a conflict between tools.
- Outdated WordPress, PHP, or Plugin Versions
Visual Composer needs a certain PHP and WordPress version to run properly. The builder might not function if your website is running an outdated version.
Also, using an outdated Visual Composer plugin can lead to errors. When updates are skipped, bugs and security flaws stay in place. This causes the builder to crash or not respond.
- Low Server Resources or Memory Limits
Sometimes, the issue is not with WordPress or plugins. It’s your server. Visual Composer is a powerful tool. It needs enough memory and server power to load.
If your web hosting has low memory or timeout limits, the builder may fail to load. This often results in a timeout error or an incomplete page load.
- JavaScript or jQuery Errors in Browser Console
Visual Composer runs on JavaScript. If there is a script error, the builder can break. These issues often show up in your browser console. You may not see a clear error on the screen, but the builder simply won’t respond.
Common signs of JavaScript issues include:
- Page freezing while loading
- Drag-and-drop features not responding
- Buttons that stop working after one click
- Broken Shortcodes or Page Data
Sometimes Visual Composer fails due to broken content. This includes damaged shortcodes or missing layout data. It often happens when switching themes or migrating sites. If page data is incomplete, the builder won’t load that page properly.
Step-by-Step Troubleshooting Guide for Visual Composer Not Working
If Visual Composer is not loading or behaving strangely, don’t worry. The majority of problems can be resolved with a few easy measures. Take it step by step with this guide. To try these fixes, you don’t have to be a developer.
Step 1: Clear Your Browser Cache or Try Incognito Mode
Sometimes the problem is local. It’s possible that an outdated version of the page is loading in your browser.
- Clear the cache and cookies in your browser.
- Try using private or incognito mode to access your website.
- Try using a different browser to see if the problem persists.
This helps in ruling out issues caused by the browser.
Step 2: Disable All Plugins Except Visual Composer
Plugin conflicts are common. Disabling other plugins helps you test for conflicts.
- Go to your WordPress dashboard
- Navigate to Plugins > Installed Plugins
- Deactivate all plugins except Visual Composer
- Check if the builder loads correctly
Reactivate each plugin one at a time if it works. The one that breaks the builder is the conflict.
Step 3: Switch to a Default WordPress Theme
Your active theme might not be compatible with Visual Composer.
- Go to Appearance > Themes
- Set a default theme, such as Twenty Twenty-One, to active.
- Try using Visual Composer to edit a page.
If the builder works now, your original theme may be the issue.
Step 4: Check for JavaScript Errors in the Browser Console
JavaScript errors can block Visual Composer from running.
- Open your website
- Click F12 or select Inspect with a right-click.
- Click on the Console tab
- Look for any red error messages
If you see script errors, a plugin or theme may be breaking JavaScript.
Step 5: Update WordPress, Visual Composer, PHP, and All Plugins
Compatibility problems are frequently caused by outdated software.
- Verify that the core of WordPress is current.
- Get the most recent version of the Visual Composer plugin.
- Ensure PHP is version 7.4 or higher
- Update all other plugins as well
Check to see whether the problem has been fixed after updates.
Step 6: Increase PHP Memory Limit and Max Execution Time
Low memory or timeout settings can stop Visual Composer from loading.
- Edit your wp-config.php file
- Add or update the following lines:
define(‘WP_MEMORY_LIMIT’, ‘256M’);
set_time_limit(300);
- Save changes and reload your site
- Check if the builder now loads correctly
Ask your host for assistance if you’re uncomfortable making changes to files.
Step 7: Enable WP_DEBUG to Catch Errors
A built-in debug mode in WordPress can uncover hidden issues.
- In wp-config.php, find the line define(‘WP_DEBUG’, false);
- Change it to:
define(‘WP_DEBUG’, true);
- Visit the page with the issue
- Check the screen for any error messages.
These signals can assist in identifying the precise issue.
Step 8: Reinstall Visual Composer Plugin
Sometimes the plugin file gets corrupted. It might be fixed with a new install.
- Remove the Visual Composer plugin and deactivate it.
- Get the most recent version from the vendor of your plugin.
- Reinstall and activate it.
- Try launching the builder.
Before removing the plugin, make sure you have a backup of your website.
Most users can resolve their Visual Composer issues by following these instructions. If none of these work, it may be time to consider advanced solutions.
Advanced Fixes for Visual Composer Not Working
It’s time to move on to more complex repairs if you’ve done every basic step and Visual Composer is still not loading. These solutions require a bit more technical access, but they are still manageable for most users or developers.
Step 1: Check Your PHP Version and Upgrade if Needed
Visual Composer needs a modern PHP version to function smoothly. Not all of the builder’s features may be supported by older versions.
- Enter your hosting panel (such as SiteGround tools or cPanel).
- Find the PHP Version Manager or PHP Selector
- Verify that PHP 7.4 or greater is being used.
- If not, upgrade to a supported version
- After upgrading, test the builder again
Using outdated PHP can lead to a Visual Composer fatal error during load.
Step 2: Review and Adjust Server Timeout Settings
If your server is too slow or has strict limits, Visual Composer may time out.
- Use your hosting dashboard to access PHP settings
- Look for options like max_execution_time and max_input_time
- Set both to at least 300 seconds
- Also, increase memory_limit to 256M or more
These settings reduce the chance of a Visual Composer timeout error.
Step 3: Examine Error Logs on Server
Server error logs can show issues that WordPress doesn’t display.
- Access your error_log file from your hosting control panel
- Check for messages related to vc_vendor, vc_templates, or fatal PHP errors
- If you see errors about memory or plugin conflicts, note them down
These logs can help your host or developer resolve deeper issues.
Step 4: Roll Back to a Stable Version of Visual Composer
Sometimes the latest plugin version causes conflicts with other tools or themes.
- Turn off the Visual Composer version that is currently installed.
- Remove it from your list of plugins.
- Download an older, stable version from the official source
- Install and activate it
- Check if the issue is now resolved
Rolling back often fixes Visual Composer editing broken or crashing problems.
Step 5: Test with a Staging Site First
Use a staging environment before making modifications to your live site.
- Most web hosts offer one-click staging tools
- Clone your site to the staging area
- Apply updates, try fixes, or switch themes there
- Test the builder carefully before copying changes to the live site
Staging avoids website downtime during troubleshooting
Step 6: Check File Permissions and Ownership
Incorrect file permissions can block Visual Composer from saving or loading.
- Utilize your host control panel’s file manager or FTP
- Verify that the permissions for wp-content/plugins/js_composer are 644 for files and 755 for directories
- Correct permissions if needed
- Refresh your website and check the builder
Wrong permissions can cause hidden issues during plugin execution
If you’re still stuck after trying these advanced fixes, the problem might be very specific to your setup. The best course of action in that situation is to speak with your hosting support or a WordPress developer.
How to Prevent Future Visual Composer Issues
Once you’ve fixed Visual Composer, it’s important to keep it stable. Many problems come back if you don’t follow safe site practices. These steps will help you avoid future issues.
Step 1: Keep Everything Updated
Bug fixes and improved WordPress compatibility are frequently included in updates.
- Update WordPress core to the most recent version at all times
- As soon as a new version of Visual Composer becomes available, update it
- Regularly update your theme and associated plugins
Using outdated tools is one of the main causes of plugin issues.
Step 2: Test Changes on a Staging Site First
Never make significant modifications to your live website directly.
- Use a staging site to test plugin or theme updates
- Check if Visual Composer works well after changes
- Only apply updates to your live site if everything runs smoothly
This step protects your site from unexpected breakdowns
Step 3: Limit the Number of Installed Plugins
An excessive number of plugins might cause issues and slow down your website.
- Only use plugins that are essential
- Avoid installing plugins with overlapping functions
- Remove any plugin you’re not actively using
Fewer plugins mean fewer chances for Visual Composer to break
Step 4: Choose a Reliable Hosting Provider
Cheap or shared hosting can cause timeout and memory issues.
- Pick a host that supports WordPress performance
- Look for features like increased PHP memory and one-click staging
- Make sure they offer fast and helpful support
Good hosting reduces many technical problems before they start.
Step 5: Regularly Back Up Your Website
Before making any significant changes, always make a backup of your website.
- Use backup plugins like UpdraftPlus or your host’s tools
- Keep backups on cloud storage services like Dropbox or Google Drive.
- Set up automated backups at least once every seven days.
In the event of an emergency, backups enable you to promptly recover your website.
These procedures will shield your website against Visual Composer problems in the future. Prevention is easier than fixing problems again and again.
