While waiting to rebuild the MySQL data table that houses the Sevengates Newsletter the dysfunction in the Sponsor Overview pages has been repaired. The following panels are now fully functional: Your Data and You, Sponsor Overview, Event Profiles, and Splash Panel.
The Word Cloud functionality will remain dysfunctional until the MySQL data table has been restored, and the lack of correspondence between the number of Unique Visitors and Total Visits in the Graphs and Charts panel remains an unsolved mystery.
The corrupted MySQL data table appears to be related to the overall performance of the site. This problem is currently under investigation.
