This bug is awfully persistent. I am attempting to add a forum that records articles from the BBC News UK Edition, (http://feeds.bbci.co.uk/news/uk/rss.xml). When saving/previewing this feed I get a message popup titled "Uncaught Error", with a rather non-descriptive piece of information; "An unexpected error occurred. Please try again later.". I've tried different combinations of feeds, from a range of websites, and a combination of URL's to access them (Those specific to an .xml file, and those without) all report the same. The server error log is empty, and I'm essentially stumped as to what the problem is. Im running the RC1 candidate if that makes much of a difference. (EDIT: After further searching the forums, URL's and feeds reporting to be working by users also fail with this error, or get accepted yet import nothing.) Thanks in advance, Lyndon.
