Fatal Error when opening page in WP backend

  • Hello,

    we cannot edit pages in WP backend any more – fatal error. The debug.log file says:

    When we switch to a default WP theme the error is gone, so it must come from Enigma Theme.

    Please help. Thank you.

    Hello and thank you for your reply.

    The issue still exists.
    Error message –> screenshot: https://ibb.co/PF9Bg2M

    Meanwhile I found out how to bypass the issue by changing a line in each of two widget files:
    /wp-includes/widgets/class-wp-widget-media-gallery.php. —> line 82
    /wp-includes/widgets/class-wp-widget-media-image.php —> line 70
    Changes –> screenshot: https://ibb.co/N1ppgmN
    This is of course only a temporary bypass since with the next plugin update the changes will be overwritten.

    Hello @raininger ; I will not suggest you to edit WP’s core files.

    Thanks.

    I know that. That’s why I wrote that it’s only a temporary bypass. I hoped you would tell me how to fix it, that’s why I asked for support here.

    @raininger : Best Practive would be —
    1) Take Proper Backup ; Remove any malicious files or folder.
    2) Take backup of DB as well.
    3) Install a fresh WP setup on new fresh hosting.
    4) Enable all required Plugins-Themes always remember to add Security plugins on WP site.

    Thanks
