Upon upgrading my blog to 3.3.1 I immediately noticed that my Visual and Html controls were gone in posts and pages.
After reviewing many different ideas about what could be causing the problem, I tried a list of solutions including recompiling php as I have a dedicated server.
Finally, after suspecting the config file, I edited the config file to add the following statement:
define(‘CONCATENATE_SCRIPTS’, false );
… And now my controls are working.
