The admin doesn’t allow saving the user when he has a homepage URL. This is because the software strips the http:// part for saving to the database AND displaying in the admin, although it actually checks if it is there when saving. Additionally, no error messages are shown so it looks as though the 'save' button doesn't work.
I've done a really simple edit adding the http part in showuser.php but this is a dirty fix, as some people might require eg. https:// instead of http://
I think it would be good to go through all files and fix this throughout the entire soft.
