I've just spent 30 plus hours working on a website poweder by WordPress.
Up until last evening the Rich Text Editor had been working flawlessly.
At some point during one of my final sessions I re-entered Manage Pages to find that the Visual Text Editor was not displaying and the edit page appears stuck in CODE editing mode.
I've spent a LOT of time last evening and today trying to find a solution to what is A VERY OBVIOUS BUG only to find too many unresolved support posts and no really solutions.
I've verified my WordPress installation.
I am using the following plugins: Search Everything, ShiftThis - Order Pages and WordPress Database Backup. All have been installed for quite some time without any problems.
I have tried the Prototype.js Recursive Fix.
I have re-uploaded my Includes folder.
And now I am completely stumped.
I was hoping to turn the website over to the client today or Wednesday but I can't until the Rich Text Editor is working properly.
