Select2 javascript error

Or, maybe it’s an error in ACF.

Either way, it’s causing a javascript error, and that error is causing other errors

This is still a problem.

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.
