Hi all, sorry for bothering you with sth that is clearly a case of rtfm-and-do-what-it-says.
An upgrade on a previous server failed because of an insufficent PHP version.
This happened inmidst of upgrading V2.0-rc1 to V3.7.0.
Now, I tried moving all files in piwikstats/* and the database to a new, more adequate server (running PHP 7.3).
did, finally, update the Database, but then crashed with the message
Uncaught exception: Class ‘Piwik_Plugin’ not found
in …/piwikstats/plugins/DoNotTrack/DoNotTrack.php line 20
Can someone suggest further steps?
Thanks a lot!
