Error when opening Event Console

I am unable to open the Event Console in Zenoss version 4.24. The error message I get is listed below. I have ran the following commands to try and troubleshoot the problem findposkeyerror, zodbscan, zenrelationscan, zencatalogscan which
are returned with errors. I have inherited zenoss from a previous user and still don't know alot the configuration of zenoss.
Any help would be greatly appreciated. I can look at other pages in Events (ie: Events Archive, Event Classes and Triggers. I
can also see the events for a device if I select Infrastructure and then select a device and then click on the error box on top. I
can also acknowledge the events for the Infrastructure page.

Here is the error message I am receiving.
