I've recently installed WordPress 1.5.2 by upgrading from a b2evolution blog. Everything went well (except some minor bugs). However, I have one that bugs me (no pun intended).
When trying to post a comment, we are taken to a white screen and nothing happens. No comment passes through and is recorded in the DB. I have a custom skin, but it also happens with the default skin. My permalink is /%postname%/, but the problem also occurs with the default option.
I've read the other support threads, but I'm pretty puzzled, as nothing came out of them.
