My PrestaShop store relies on the “Super Speed – Incredibly fast – WebP, Cache & SEO” module. With server cache turned on the site flies, but any tweak I make inside product-related modules (typically when I change their settings) never shows up on the front end until I switch the cache off. Disabling cache solves the visibility issue yet instantly drags page-load times down. I need someone who can keep the server cache active while making sure back-office edits propagate to the storefront right away. Key facts • Affected area: product-related modules only; other sections behave normally. • Main trigger: changing module settings. • Current side effect when cache is off: slower page loading. What I expect from you 1. Audit the current Super Speed configuration, including any override or .htaccess rule that may block cache invalidation. 2. Identify why cache misses product-module updates and implement the proper invalidation or cache-busting routine. 3. Test and confirm changes update instantly with server cache enabled, without introducing new errors. 4. Provide a short report of what was changed so I can maintain it going forward. Bonus points if you: • Have resolved similar cache-sync issues in PrestaShop 1.7+ using Super Speed, Page Cache Ultimate, Varnish, or similar tools. • Can suggest additional tweaks (Redis, PHP-FPM, CDN rules) to squeeze more performance once the core problem is fixed. I can give FTP, back-office, and hosting panel access right after we agree on the approach. Let me know your estimated turnaround and any specific information you need up front.
