Session error: "Query error: Commands out of sync; you can't run this command now..."

I mean is the data in the SQL input statement good data... or if you were to run the query directly in the database (phpMyAdmin) would it work or would it give you an error?

I now run both last such error queries directly on DB (it was update of the time for the session ID and release lock) and both successfully run. Means there was a session with such an ID. The release query worked successfully but returned NULL, probably should return NULL as this is some kind of lock release.

So no, all seems good here.
