Usually it's because of certain characters in url's, such as too many ampersands. I had the problem regularly trying to put downlaod links to darkstars threads in the enws and gave up putting darkstars.co.uk up instead....
Thannks AF, that helped. I just reset it to how it was before (and as v4 of Pimped edition is now standard with Spring, the news I wanted to post is outdated... ).
