I've just created a new post with something like </a></a></a></a> as a title and content and that kind of bugged the news manager: Was not able to delete the file, it was named .xml and deleting it from my /data folder with root didn't work.
Solved the problem by going to url/admin/load.php?id=news_manager&edit=
(as the file had no name, that was the only way to edit the post)
