I am hesitant to say that I have good news or that I have fixed anything...
I honestly don't know if there is anyone left still using this site after all the problems we've had.
That said, I noticed that there were some very recent (as in yesterday/today) commits to the development branch of kbin that look like they address the issues that fedia has been experiencing. I moved fedia to the development branch and reloaded some things, and so far, no error 500's.
But, caveat emptor, we are on the development branch of early-in-its-lifecycle open source software.
Yay, Jerry, you are awesome! It was working somewhat better (but still many 500s, could at least browse the main thread listings) since the updates a couple of days ago, and now I can't get it to fail at all. Hopefully it's fixed. Appreciate all the effort you have put into this, really liking the kbin experience so far.
Thanks. I am cautiously optimistic. I thought I had it fixed at least half a dozen times in the past, but it looks good so far.
