Before you give me your default answer about browser cache, I’d like to mention that I’ve tried 3 different browsers. A very old version of internet explorer works, but does NOT display the Youtube tinymce button. Both chrome and firefox do NOT display any type of WYSIWYG tinymce toolbar.
Did you ever find a solution to this?
I’m having this same problem, is there a solution?
i edited my .htaccess file and got it working.. i don’t really know how i solved it honestly, but its working now with the help of a google search for “.htaccess rewrite rule” and some copy and pasting.
