That depends on the kind of page (main wiki / forum) and which editor you use ("classic" / "visual"). If you start editing the item that you added the URLs to, and switch to the Source editing mode, you may be able to see the links, and figure out what you need to delete. It can't hurt to try; in the worst case, you just don't save any changes. Apart from that, I'll need more information.
