Blank screen today

Hello,
Just a short note that may help some.
This morning, I could not access my piwik installation. Just a blank screen. No 404 or 403, no error message just a blank page.

I enabled the logs to “file”, but nothing.

Piwik has been updated to 1.6 a few days ago and everything went well so far.

I was able to fix the problem by resetting the /tmp folder.

I renamed the previous /tmp (for backup if something goes wrong), then created a new one, taking care to allow write access to the web server.

Thanks for the report, there seems to be quite a few users having problems with tmp folder we will try to improve this in next releases: Error "unable to start session" instead of a proper error message · Issue #2717 · matomo-org/matomo · GitHub
