Thread:Project:Support desk/upgrade from 1.16.1 to 1.21.1 failing/reply (2)

Well, this is ironic, considering how carefully I made certain everything worked on a test PC before trying it on the real server. I have now restored my DB from the system backup in case my own backup had any issues (it did not report any) and restored the 1.16.1 file tree, but I still now get "wiki_name has a problem Sorry! This site is experiencing technical difficulties". No indication whether this is a DB issue or some file is unhappy. Of course, both should be identical to what was working before I started.

I guess I'll try to do a fresh install and go from there. Did you mean a fresh install of 1.21 then just run update, or did you freshly install 1.16 (which matched your existing DB) and then try to run update?

thanks
