Can't access Matomo in browser after Ubuntu 22.04 upgrade


I just upgraded my server to Ubuntu 22.04. I can’t access to Matomo anymore after the upgrade.

I have read this other post. It seems my problem is similar, I also had an issue with PHP (new PHP version on my system was 8.1, whereas the apache mods-enable still contained the older PHP v7.4).

PHP now seems properly setup: I can browse my.server.ip/info.php and see the PHP page. But I still can’t access Matomo, I only get a blank page.

Do you have any idea how I can fix this issue?

Many thanks in advance for your help,

I finally manage to fix this issue.

Prior to that I had backed up my data just in case, using these instructions:
