The only way that error could possibly occur would be if you have no chat frames which would be virtually impossible if you have no WTF folder. Something is very broken.
I'm going to ask you to humor me and follow the instructions in this FAQ:

If you are still getting this error after doing that, please take a screenshot of your display immediately after logging in and post the entire screenshot unmodified so I can have a look at the entire layout and see if I can spot anything that's out of place.
