Hi @DarkLite25 !

This may be happening if you are using PHP8+ as there are several deprecated and revised functions affected since this CMS was built with PHP7.

If you're comfortable rewriting some PHP code, you could try your hand and work through the affected functions that are presenting an error. This won't cover everything that requires attention but would be a good place to start.

To assist you, here are a couple tips to help get you started:

Issue:
Deprecated: str_replace(): Passing null to parameter... and Deprecated: preg_replace(): Passing null to parameter...
Possible Fix:
Replace null with '' in each instance

Issue:
Deprecated: usort(): Returning bool... and Deprecated: uksort(): Returning bool...
Possible Fix:
Returning a bool (true/false) is no longer an option, set the response to be an integer by placing the return value inside an intval function.
Example: return intval(strlen($a[0]) < strlen($b[0]));

Otherwise, for the quick and easy fix, change the version of PHP you are using to 7.4 but please be aware that this version of PHP has reached end-of-life since 28 Nov 2022 and so would not be ideal for production systems, especially those open to the public (internet accessible).
