Oops! an error occured

[EyelessArseFace]

I keep getting this error message when I try to open a thread called "What's the most bonkers thread you've read on here?". Everything else is fine except this one thread. It says:

Oops! an error occurred
The server returned a "405 Method Not Allowed".
Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

Any ideas? I've tried to open it three times now, and the third time I refreshed the screen and it opened. But there must be some issue somewhere, and since it says to let you know - well here we are.

I'm using a laptop and Chrome.

It's funny that other people are having the issue, yet don't get the same error message appear in the box as I did. More than one glitch in the matrix, maybe.

Thanks for all of the extra information, everyone! We've identified the issue and will have it fixed ASAP.
