I went to my Events page in Orion and everything worked as expected. I then specified some filters and clicked Refresh on the Events screen and received the appended error screen.
After a few different tries I found that it doesn't seem to matter which filters I use, even if I don't use any and just click Refresh I get the same error. The rest of the system appers to be functioning normally including the database and access to the database.
Any suggestions here would be greatly appreciated!
