The tabs HTML and Visual are not responding at all. Clicking on them does nothing and the editor is stuck in HTML mode.
I have searched the forum and found several posts about this problem occurring on 2.5 and 2.6. One of the solutions offered was to ensure that the use visual editor option was checked in the user profile.
I cannot seem to locate the "use visual editor" option in 2.7. Is it there? If so, where please?
