Warning

Just noticed this warning message at the bottom of my recently scheduled revision:

Warning: Missing argument 2 for Tinymce_Advanced::mce_buttons_1() in /home/gretche4/public_html/wp-content/plugins/tinymce-advanced/tinymce-advanced.php on line 489

Here’s a screenshot: https://www.dropbox.com/s/pixjx6u067wnd09/Screenshot%202016-10-06%2017.08.36.png?dl=0

Is there something I need to fix?

Thanks,

Caitlin
