Just thought I would post this in case anyone else ran into this problem. My visual editor in Black Studio TinyMCE stopped working. I would drag the widget over, it would open up the visual editor would display for 2 secs and then disappear. The visual tab greyed out. The entire menu in the editor just vanished.
I do have Ultimate TinyMCE installed as well but no conflict there. Posts/pages the visual editor showed and worked fine.
I discovered it was the Youtube Channel Gallery plugin causing the problem with Black Studio TinyMCE widget plugin not working. Disable Youtube Channel Gallery and all is fine again.
