Hello there, we have tried upgrading Piwik to Matomo 3.12.0 but after the
php console core:update command we had some problems:
php console diagnostics:run gives back no relevant errors. I've attached screenshots of the web gui.
Hello @tsteur the problem with empty action in Proxy module was solved with your patch.
(I applied a raw brutal cut-n-paste in the code)
I think the problem with CSS was given by the notice error html output before sending real headers to the client, so it was missing text/css content type or something like that.
Thank you team for fast caring :top:
