I fixed the style problem it was where I had not done the layout fix & store css as files fix right in this post
https://vborg.vbsupport.ru/showthread.php?t=249120.
I just noticed if I turn off the arcade in the arcade settings it shuts it off ok no one can view it except admin with the message ! Arcade Offline ! so that works ok but you still can't disable the plugin.
Looking at this page
https://vborg.vbsupport.ru/showthrea...=269346&page=2 it looks like a few people are having the same problem.
Thanks again for the help.
