    I recently had to rehost my website manually from backups. I had to reinstall or reactivate all of my plugins including Wordfence, but it threw a fatal error
    Fatal error: Uncaught Error: Call to undefined function filter_var() in /home/dh_6usrzb/tlinwright.com/wp-content/plugins/wordfence/waf/bootstrap.php:177 Stack trace: #0 /home/dh_6usrzb/tlinwright.com/wp-content/plugins/wordfence/waf/bootstrap.php(150): wfWAFWordPressRequest->_isValidIP(‘24.176.156.161’)

    The IP address shown above is not to my site but to my personal device. I had the full database backed up as of Dec 20, and rehosted Dec 22. It installs fine but fails at activation.

    Hi @irwintheresa,

    Can you verify that the PHP version on your new host is 5.2 or higher?

    The error message in your post indicates that the filter_var function is missing, which is the case with versions below 5.2.

    I have it at 7.4 FastCGI per my settings.

    As an update, the new version activated without any errors. I still have no idea why it was breaking, but it’s working for now without any issues.
