Having same problem as listed above. Running Vantage Premium Theme from SiteOrigin with WP 3.8. Installed and activated Black Studio TinyMCE Widget ( did not see or understand the whole click on the arrow and not the name thing ) Browser is Safari.
I tried to do the CSS fix but without luck. In the editor when I would select plugin to edit black-studio-tinymce-widget/black-studio-tinymce-widget.css The name would come up at the top with the word (inactive) at the end. This was true whether the plugin was activated or not.
Does this mean I haven’t activated the plugin properly and, if so, how should I do it. I’m very new at this and only know to click “activate” in the plugins page.
