My store is still running on an older OpenCart 3.x build with PHP 8.0, and I’m seeing growing security warnings and scattered extension errors. I want to move to the latest stable OpenCart release on a fully supported PHP version, then bring every critical piece—starting with the Universal Import/Export Pro tool—back into perfect working order. Here’s what I need from you: • Upgrade the OpenCart core to the newest, stable version available. • Update the server’s PHP to a version officially supported by that OpenCart release. • Keep Universal Import/Export Pro fully functional after both upgrades. • Bring all other essential extensions and my custom theme up to date, fixing or replacing anything that breaks. • Run a full compatibility check on every remaining module, theme tweak, payment gateway, product-management add-on, and customer-support integration so I can be sure there are no hidden conflicts before we push live. I’m not certain which smaller extensions might need attention beyond those listed, so please flag anything outdated during your audit and include it in the upgrade path. Proven experience upgrading OpenCart installations and hardening PHP environments is a must; I’ll lean on your judgment to keep the storefront stable, secure, and future-proof.
