Almost every time I try to access certain threads, I get 502 errors. For example, http://www.everypony.com/forums/showthread.php?14135-Share-your-Tumblr. It's weird because it worked for me once, and I was able to post, but upon posting, I got a 502 again and I can't get it to stop. I can't really tell what it is that prevents me from viewing select threads. I think the ones that give me issues are new threads, made in the past day or 2. On another note, for the past couple of days, every post I make using Quick Reply is a double post, and I have to go back and edit out the second post. EDIT: The problem with 502s was my cookies/cache. Thanks to Mike for the help on that one.
I'd like to make it clear with staff that should be reading this. That these are server errors, and clearing the cookies only allows you to get a completely new session, from being force logged-out and is only a temporary solution. It will happen again. I'm quite certain that Ghan properly logs activity on the server including if there are an abundance of errors. It might be wise to get in contact with him on the subject to see if he can give any insight or perhaps a fix. I've read from a few sources that 502's can be common on vBulletin installs that reside on a server running NGINX (which EP does).
