right look at the URL in the browser, it has the access check variable twice:
?accesscheck=%2Fclients%2Faccount%2Findex.php%3Faccesscheck%3D%252Fclients%252Frooms%252Findex.php%253F
this means that the /clients/rooms/index.php page is set to redirect to the /clients/account/index.php page if access fails, and the /clients/account/index.php page redircts to the login.php page.
since it directs to the /clients/account/index.php first, that is successful lgin page.
on the /clients/rooms/index.php page, set the failed redirect to the login page instead.
