I have spent some time investigating this nginx thing and most the stuff I came across points to it being a tool used by web sites for various reasons like file handling, reverse proxy & load balancing. Could you please tell tell me if the Arduino site(s) use this tool.

Riva: Could you please tell tell me if the Arduino site(s) use this tool.

Yes.

I have a theory but cannot test it myself. If you create a new topic and list it in the unread posts (but don't go to it) and then move/delete the topic using a different browser tab/window. Flip back to the unread posts tab/window and then try going to the topic, does it throw up this message?

No. Works fine.

Right.
