Web Reports - Unable to access Reports List

Having an unknown issue occur with BigFix Web Reports. I am not sure what may have caused this, but I am suspicious of some custom reports that some users may have imported. I can log into WebReports no problem, but if I try to browse the Reports List, I receive the below error.

Unfortunately I am not sure exactly when this started happening, I only noticed it yesterday. Is there a way to remove and rebuild the WebReports database?

Successfully resolved this issue by deleting all users I suspected of importing bad custom reports and deleted all of their reports.
