I followed your instructions (Cache and Editor) and switched the editor to TInyMCE. Then I attempted to start a post and got the following error message:
There are no "TinyMCE" option avail to be selected unless youve edited the templates and removed the admin HIDDEN flags from them. TinyMCE and SCEditor are hidden for a reason. they are not complete and none of their required dependancies are included in the release package.
The errors you are getting by eneabling incomplete and unsupported features are why those two options are hidden and disabled from use.
