https://www.php.net/manual/de/migration74.deprecated.php
The get_magic_quotes_gpc() and get_magic_quotes_runtime() functions are deprecated. They always return FALSE since PHP 7.4

What are the steps to reproduce this issue?

1. Open SourceBans++ and browse to the public serverlist.
2. A popup with multiple deprecated warnings depending f.e. includes/xajax.inc.php is showing up.

There are actually multiple places where get_magic_quotes_gpc() and get_magic_quotes_runtime() is used in the code right now.
