Sidebar Pro – All sidebars stop showing: Error included

I was working on my side in the Admin posts and noticed all my sidebars are defaulting to the theme sidebar. The checkbox is check to “Allow overide of this sidebar.” Didn’t load any new plug-ins or anything like that. Deactivated the sidebar plug-in and reactivated.

I found this error:

PHP Warning: Missing argument 2 for apply_filters(), called in /var/www/sites/www.cask.com/wp-content/plugins/custom-sidebars/inc/class-custom-sidebars-visibility.php on line 531 and defined in /var/www/sites/www.cask.com/wp-includes/plugin.php on line 177, referer: http://cask.webbege.com/wp-admin/edit.php?post_type=page
