Piwik's site isn't available any more

Hey guys!

I hope you can help me with my problem. Since yesterday, the piwik site of the website i was tracking, isn’t available anymore. This means, that there is just a white site without any content or something. The piwik tracking code somehow disappeared from the website yesterday afternoon (i embedded it via a typo3 extension) but in the morning, everything was working fine. So i embedded it again to the website - not via the extension but manually. In spite of, nothing happened and my piwik site is still just white.

Do you have any suggestions for me how to solve the problem?

Greets!

okay, got it! i should have read the FAQs first.

deleting the stuff in piwik/tmp fixed it.
