@pummelchen Thanks for the response.
Ok for the solution, but If that's true, it's still strange behavior. My forum is in a test period so indeed it doesn't have much traffic, but I come by at least once a day to see just how frequent the error is. It means that if we go on vacation and nobody visits our forum for a few days, when we get back all the owners of a forum under nodeBB have chances to see this error? That's annoying.
