XF 1.5 Thread link diverting to Index.php

[ElgrandOC]

Right then guys and gals... not entirely sure what is happening here, but I've got a problem that I am unable to resolve with my limited knowledge.

Try clicking the link below. This SHOULD take you to the thread content. However, all it does it link back to the index.php forum menu. I cannot get access to this thread at all no matter how I've tried.

Can anyone help?

Do you have any custom rewrites set up?

The other threads either side of it load fine.

The first URL is returning a 302 response, which we wouldn't typically do with that. But further, the response headers don't indicate that XF is actually being hit, so it must be a redirect being triggered before XF (or likely PHP) is started.
