Incompatibility with Codepress Admin Columns

Hi Sweet Homes,

The creator of that plugin has used the admin_body_class hook incorrectly and the error is his/her fault.

Replace admin_class in codepress-admin-columns.php with:

function admin_class($classes)
	{
		global $current_screen;

		// we dont need the 'edit-' part
		$screen = str_replace('edit-', '', $current_screen->id);

		// media library exception
		if ( $current_screen->base == 'upload' && $current_screen->id == 'upload' ) {
			$screen = 'media';
		}

		// link exception
		if ( $current_screen->base == 'link-manager' && $current_screen->id == 'link-manager' ) {
			$screen = 'links';
		}

		// loop the available types
		foreach ( $this->get_types() as $type => $label ) {			

			// match against screen or wp-screen
			if ( $type == $screen || $type == "wp-{$screen}" )
				return $classes . " cp-{$type}";
		}
		return $classes;
	}

I’ve posted a topic on the support section of his plugin, telling him how to fix it.

Cheers, Jake.

You are right. I forgot to return the $classes from that admin_class filter. I will fix it in the next release. Thanks for spotting that!
