TinyMCE Advanced- Can't access VISUAL editor, only TEXT

Hi,

I had Advanced TinyMCE installed and it was working. Had been tweaking the .htaccess file because of permalinks issues (still unresolved), and suddenly, I can’t access the Visual text editor, only the HTML side (or TEXT).

I deactivating all my plugins, which did not help. Then reactivated just the TinyMCE plugin, still didn’t help.

Site is tropicmodel.com. Is there an easy way to fix this?
