[wp-forums] "502 Bad Gateway" error when attempting to view forum posts

[Siobhan Bamber]

Hey.

I keep returning a "502 Bad Gateway: Nginx" error message when attempting
to view individual posts on the Support forum. I've attached a screenshot
showing the exact error message.

I can view the listings of the posts fine, it's only when clicking on the
title of a post that this error shows.

This has only started happening today, and I don't seem to be having any
trouble accessing any other pages on the web.

I've gone through all the basic checks - clearing cache, changing browsers
etc. and have also tried to Google some solutions.

I'm at a bit of a loss. Has anyone else ever ran into this sort of problem
with the forums before? Does have any ideas on how I could resolve this?

Many thanks,

Siobhan
