I’m trying to import old google analytics data into a wordpress site but I’m having problems even accessing the “import” section within Matomo admin. The image below shows my issues:-
There was a bug in the plugin that required a change in Matomo to fix. This fix has been included in the next Matomo release which was originally planned to be 4.1.2, but then became 4.2.0.
Matomo for wordpress hasn’t been updated to Matomo 4.2.0 yet (it is still on 4.1.1) as it is waiting for a few bugfixes that will be included in the next few days in 4.2.1.
So if it isn’t urgent, I’d recommend you to wait for a few days.
