A recent PHP upgrade activated an installation of SSU/USU and is now preventing the store from loading. The Admin area is accessible, but there's not a module listing within Admin > Tools. The site was separately migrated to a new Linux hosting plan using PHP 5.4 and MySQL 5.5 and the administrative area and storefront are both inaccessible. The migrated site was additionally updated to v 1.5.4 without any change. The database was further updated to reflect v 1.5.4 and it's just a WSOD on the storefront.

I reviewed the information in an old thread https://www.zen-cart.com/showthread....URL-completely without any further success.

Does anyone have any further suggestions? We're not quite at the stage of utilizing the SEO URL configuration, but if it can be uninstalled and then re-installed, that would work as well.

I appreciate any assistance in the interim.
