Same – seems to be linked to the Black Studio TinyMCE Widget?

Hi guys. I seem to have found a temporary fix for this.

In black-studio-tinymce-widget.php, line 163, comment out

$initArray['theme_advanced_buttons1'] = str_replace(',wp_more', '', $initArray['theme_advanced_buttons1']);

Seems to fix the issue.
