Hey there, Spermy.
Can you toss me your ticket number again, so I can write a more detailed response in there instead of GFY?
It's odd that this isn't happening on anyone else's installation. If that IS the case, I'd love if people would contact me directly and let me know, so that we can see what the issue might be.
If it's JUST this one box, and it works for you on any other box (i.e., if I set you up on my box), then it's fairly easy to troubleshoot -- it's somehow the environment, right?
Oddly, I'm on the same host, as are many other ABP users, and not having that problem. Can you give some more specific examples (i.e., the FEED you pulled, the BLOG you're posting to, etc) in the ticket (if you submitted one)? I'll run the same settings on mine and see what we get.
