O.K. I have found the reason why the ChatBox will only work with ONE theme.
For some reason this template
mgc_cb_evo is not being removed during the UNINSTALL and/or is not being updated with a fresh install or update.
Here are the files... The first is the NOT UPDATED and causing the ChatBox not to load properly, The CORRECT version is in my next post as I exceed the text limit when posting both here.
Code:
