Your plugin has been throwing those 2 errors for about a couple months intermittently now. I don’t know how to replicate it or when it’s happening. I just keep seeing it in the error_log.

Just off eye inspection alone, you can see that after the 2nd AND in the query there’s a “mt3user_login” which seems like an error since “mt3” shouldn’t be there. Furthermore, in that same line you have a “OR .meta_value = ‘travis'” where it seems like the “mt3” should be just before that dot (which is what the 2nd error is complaining about). I’m not sure how this query has passed your testing or how it’s been running all this time without causing massive issues.
