Cannot Edit or Delete WPFORO posts

All of a sudden, for the past few days, I have been unable to edit or delete posts in my WPFORO forums, which had been working previously.

I turned on Wordpress debugging and get these errors in debug.log when I try to edit or delete:

I have tried deactivating other plugins but that does not correct the issue.
