It seems this module isn't working on PHP 8.0 as I get this error:

Call to undefined function get_magic_quotes_gpc()

Research on php.net confirms:

This function has been DEPRECATED as of PHP 7.4.0, and REMOVED as of PHP 8.0.0. Relying on this function is highly discouraged.

Are you going to make this module PHP 8.0 compatible?
