Piwik not counting correctly after update to 0.4.5

After upgrading piwik from 0.4.4 -> 0.4.5 (manually) the visits are not counted correctly.
It seems that only direct hits are counted, referers and search-engines stay blank in the dashboard.
Is there something to do? My error log reports no error.

BTW: Everything worked fine with version 0.4.3, then there was a 2 Step upgrade 0.4.4, 0.4.5 …

Solved the problem. A 3rd party plugin caused that error.
