Or, maybe it’s an error in ACF.
Either way, it’s causing a javascript error, and that error is causing other errors
I just started seeing this same issue. Only on one of several sites with both this plugin and ACF though… curious.
You can put this in your functions.php file.
// Fix WP Notification Bars bug.
add_filter( 'mtsnb_force_bar_post_types', function() {
if ( is_admin() ) {
return [];
}
return [ 'post', 'page' ];
}, 10, 3 );
The draw back is it disables page by page controls, but most of us are only using the site wide option anyway.
I had forgotten that we figured out the workaround 2 years prior.
because it’s still a problem.
