This just happened to me too. I upgraded from 3.14.0 to 3.14.1 - a minor release with bug fixes only.
Now, it’s given me a great error:
An error occurred
To run Matomo you need at least PHP version 7.2.5
Unfortunately it seems your webserver is using PHP version 5.6.32.
Please try to update your PHP version, Matomo is really worth it! Nowadays most web hosts support PHP 7.2.5.
It’s not that I’m not against php server upgrades, it’s that this was not mentioned in the release notes. So, now I’m stuck with analytics that won’t load. Fortunately it’s silently failing, and so our 6k+ visitors a day to our app aren’t being hindered. But this is pretty bad that such a big jump wasn’t listed in the release notes - and, that the upgrade install process didn’t stop me and tell me.
Back to the drawing board. There goes the rest of my day.
Fortunately the DB is still in-tact, so I was able to upload version 3.14.0 to a new directory, and then copy across the config files.
Once that was working, I was then able to rename both paths and it was good again, and statistic data started flowing through. Still checking if there’s any plugins we are missing ,but at least it’s capturing data again.
Only thing missing was the IP2Location plugin which was a simple fix.
