Updating anata.co.il website

I’m looking for an experienced ProcessWire / PHP developer to help restore access to an old website admin panel after migration to Bluehost. The website is built on an old ProcessWire version, and the admin URL is: https://anata.co.il/pw/ After moving the site to Bluehost, the admin panel no longer works. The database exists and appears to be connected, but the error log shows: “Call to undefined function ProcessWire\get_magic_quotes_gpc()” The current hosting only supports PHP 8.1+, while the old ProcessWire installation seems incompatible with PHP 8. I need someone who can: * Diagnose the issue safely * Restore admin access if possible * Advise whether we need PHP 7.x hosting or a ProcessWire upgrade * Avoid breaking the live site * Make a proper backup before any changes Experience with legacy PHP, ProcessWire 2.x, cPanel/Bluehost, migrations, and PHP compatibility issues is required.
