Error 503 Backend Fetch

Hi everyone,

Hoping someone can shed some light on an error I'm getting. I was able to post a first chapter of a story and when I went to add a second chapter I was able to preview it, but clicking "save" gives me the following:

Error 503 Backend fetch failed
Backend fetch failed

I've tried logging out and logging in again, clearing my browser cache, and even attempted to post from a different computer. Nothing seems to help.

I had the same problem happen probably 8 months ago, I got 10 chapters into a story and then the site suddenly stopped accepting new posts, and I always got this same error. I gave up after Erin and Piper weren't able to troubleshoot it, and have been posting my fiction elsewhere. No idea why I was suddenly able to come back and post a single chapter before it started up again.

I found some older posts in the forum with this same error, but wasn't able to tell what those users did to fix things (or if they even were able to). Posting here in case someone else has triumphed over this particular annoyance in the past.

Thanks,
Paige
