@pitaj that's it! Oh gosh, I literally couldn't see the connection of that ID. But now it all makes sense.
I have a new install of NodeBB on Ubuntu with Redis and Nginx. A few users (myself included) notice that occasionally a page hangs when loading, just showing the top navigation bar and a spinning loading indicator. A reload of the page fixes the issue.
Anyone had this same problem? Any hints on what to look at?
