I have tried switching to a different theme AND deleting and reinstalling the Thesis theme and neither of these brought the toolbar back. I have deleted all plugins and also went into the file manager to ensure they are completely deleted. None of this has worked to bring back the toolbar.
I did notice that my file manager (on my web host) as a PHP filed called: .wysiwygPro_preview_0ee9202c34465d2b5ed8822771bb9aa8.php
This does not show up in the file manager on my other WordPress sites (where the toolbar is working / showing just fine). Not sure if that has anything to do with anything?
Still need help.
