Help Needed - Critical Error and Triggers
-
Hello,
I noticed that some of my contacts weren't triggering an update needed comment, so I went to Admin > Settings (D.T) > General Settings tab > Update Needed Triggers section to check on the settings.
Everything looked correct. I clicked on "Run checker now" and received an email that my site was experiencing a technical issue.
Now, when I click "Run checker now" I get this message about a critical error:

How do I fix this?
Perhaps related, around this time, I also changed the primary domain. I changed it back to the original primary domain, but I am still getting the critical error message.
