i deactivated the addon from there and deleted the files still the same problem
so i deleted the whole addon from there then deleted the files and also still the same
though the addon does not exist, the files insist on remaining there and I can't delete them to keep the site working
Have you checked the database table for it? Because if it's seeking the addon files, it's not deactivated properly.
Again, I ran into this before too, and I fixed it by finding the addon on xf_addon, and changing the 'active' field from 1 to 0, I did this with all the addon files in tact.
Once I did all that, and I logged back into the Admin panel, it had to complete some rebuilds, so I finished that, then I could see the addon on the top...
