after clicking "update" from "Edit Project" page the returned page is messed up

After I press the update button the page returned has an odd url :
http://www.noodleparty.net/jira/jira/secure/project/ViewProjects.jspa

notice that jira appears twice in the url. The page that comes back has only the actual project list on it (ie. none of the menus or the rest of the page) and looks like it has no css. I've attached the source for the HTML page returned.
