I know sometimes it could be a normal thing for that to show up because it's an invalid response from another server. But I get this way too frequently, like 4 times a day! Is this my computer or is this the whole tpt community?
I have an idea of what's causing it but can't see enough info to determine exactly. Some database tables get locked up. I can't see what queries are running to cause it though. It usually doesn't last long. I suggest ignoring it.
