Fix White Screen issue on website

I have a freshly installed CodeCanyon PHP script running on my cPanel server. Everything loads fine except for four specific links inside the admin panel—clicking any of them throws up a blank white screen. Error reporting is still off, and I’d rather you take full control of the troubleshooting and code updates.

Your job is to trace whatever is triggering those white pages, turn on the right level of debugging, patch any PHP- or MySQL-related issues you find, and leave the admin area fully usable again. Once the fix is in place, please give me a short note outlining what you changed so I can keep it documented for future updates. Access to cPanel, the script files, and phpMyAdmin will be provided the moment we start.

Documentation of installation and to fix some small issues are also availiable
