My main username is 'bw_admin'. If I visit my login page at
localhost:8888/mysite/?q=user I would be able to login but after my login I can't view the account page. Instead I get a HTTP500 internal server error. What I notice it that the underscore of my username is being deleted automatically so I would be getting
localhost:8888/mysite/?q=user/bwadmin instead of
after getting the error if I would just edit the bad URL into the URL of the mainpage of the site I can go on while logged in as admin. But it's important for future user to not have this problem so they won't panic
Here's a list of the modules that I've installed in case this might be a typical problem related to a certain module.
