I have spent the better part of the day trying to track down a problem. The website works, the database works, but starting at 7PM last night tracking is not taking place. I have verified that all communication is functional between client-piwik-database, but writing tracking information is not happening. Updates to settings and websites work fine so the database configuration is correct. There are no limits on database size. Any assistance is appreciated.
IIS log is full of the requests, just not being processed by piwik.php
IIS 7.5 (Windows 2008 R2)
