@tsteur I confirm that disabling WP-Matomo solves the problem. On my side, enabling WordPress toolbar statistics does not have any influence.
So, many thanks for your help.

@tsteur Having disabled WP-Matomo, seems to be working ! I’m investigating further…

@tsteur After having uploaded/unzip, still not working.
I have sent the system report by email.

@tsteur I see the Matomo Analytics menu item in the WordPress Dashboard.
Some (very few) functionalities seems to work (“Get started”, “Access”)

@tsteur Thanks for your quick reply.
You’re right, Matomo On-Premise is already running on my WordPress server, but it uses its own database (so I thought there was no links between the plugin and previously installed Matomo. Maybe I was wrong)

I have no access to https://github.com/matomo-org/wp-matomo/archive/updateinstalldb.zip (it seems that no “archive” folder exists), so I haven’t tried your proposal. Could you send me a new url to download the updateinstalldb.zip file ? Thanks

Have tried CREATE TEMPORARY TABLE XX –> no error message. It seems that I have the permission to do that
