    My site went down tonight after what appears to be an automatic or recent update of the PRO Elements plugin (version 4.0.4). WordPress sent me a fatal error notification pointing to wp-admin/admin-ajax.php.
    WordPress version: 6.9.1
    Active theme: xstore-child (version 1.0)
    Plugin causing the error: PRO Elements (version 4.0.4)
    PHP version: 8.1.34
    I deactivated PRO Elements via recovery mode and the site came back up. The plugin is currently deactivated.
    Please advise on whether this is a known compatibility issue with WordPress 6.9.1 or PHP 8.1.34, and what the recommended fix is. Should I reinstall a previous version, wait for a patch, or is there something else I need to do?

    Hi,

    Thank you for reaching out to us.

    Please ensure that you have installed the latest version of the PRO Elements plugin (v4.0.4.1) available at https://proelements.org/, as earlier versions may contain bugs or issues that could cause fatal errors.

    Warm Regards,
