If I enable the GeoIP2 core plugin on Matomo 4.0.5 and try to access the system check page on backend afterwards, I get the following error:
A fatal error occurred
The following error just broke Matomo (v4.0.5):
Call to undefined method MaxMind\Db\Reader::getWithPrefixLen() in /stats/vendor/geoip2/geoip2/src/Database/Reader.php line 232
Any help on how to fix this would be much appreciated!
