Frequently Asked Questions
A: A JS error or blocked AJAX endpoint usually stops updates. We restore scripts and allowlist endpoints so updates apply instantly.
A: Theme overrides or optimizer rules often break form submission. We fix templates and adjust minify/defer settings.
A: Cart fragments/cookies are cached or disabled. We re-enable fragments and exclude the right cookies/URLs from cache.
A: Product limits, sold-individually, or bad min/max/step settings cause that. We correct rules and validate stock/backorders.
A: No. We fine-tune only what’s needed so dynamic cart actions bypass cache while the site stays fast.
A: WP-Admin and, if used, hosting/CDN access to adjust cache rules. We prefer staging; live fixes are done safely with backups.
