Usually I change the admin directory in the config.php by changing something like $config['admin_dir'] = 'whatever'; but in cmsms 1.10.x I seem to miss a $config['admin'] in the config.php. Can I still change the admin directory by adding this?

Update: no such luck: I get a lot of strange "add me's" in the admin/login.php screen and whatever/login.php gives me a not found error.

How to change admin/login.php?
