You should be fine after that on thumbs
ok, now I found the time to do some testing:
I modified the usergroups as recommended, changed some settings to fit vb3 - logged in successfully and imported the usergroups.
frontend, backend, everything looked fine.
then I uploaded all 5.1 files and ran upgrade.php, all I got was a blank page containing nothing but <html><body></body></html>, all other pages as well, from frontend to backend
what do think went wrong?
I tried again with backups, but I canīt figure out what went wrong ...
