Here is an example page. You can use the login name and password of "test" (without the quotes).
When a user is logged in certain links are displayed as well as a little welcome message ("Welcome, $uname!"). However if the user clicks on links to go to different areas then usually by the third click the user name disappears from the welcome message and even though the links are still there for the users, the page acts as if the user is not logged in (ie, when you click on the links nothing happens). Is there anything I can do to fix this? Thanks. 🙂
