Meta Box

Participant

I'm not sure what's causing it either. I deactivated every other plugin when I had 1.6.18 installed and it still wasn't working so it couldn't have been a compatibility issue.

Here are the only two metabox filters I have in my functions.php :

add_filter( 'mb_aio_load_free_extensions', '__return_false' );

add_filter( 'mb_aio_extensions', function( $extensions ) {
    $extensions = ['mb-admin-columns','mb-settings-page','mb-user-meta','meta-box-builder','meta-box-columns','meta-box-conditional-logic','meta-box-group','meta-box-show-hide','meta-box-tabs','meta-box-updater','mb-term-meta'];

    return $option;
} );

Let me know if you need any more info and I can help!
