I am getting the following error message inside my widgets and above my header on the site. I am using multi site but the errors are only being displayed on http://myinsurancepage.com/.
Warning: Missing argument 2 for apply_filters(), called in /custom-sidebars/inc/class-custom-sidebars-visibility.php on line 750 and defined in /wp-includes/plugin.php on line 177
I have followed the instructions outlined in this thread but the error is still present.
