Can't Log into Admin Panel, get blank Screen

Hello,

Any tips? I can’t log into my admin panel after installing and uninstalling a plugin and changing the time zone.

The admin login page appears, but when I login, the page just goes to blank.

– My regular login is: http://www.freembb.com/wp-login.php/
– The blank page that I get after logging in: http://www.freembb.com/wp-login.php

Also, one of my pages is now blank. However, when I add a / at the end of my URL, the page loads.

– Without the / at the end of the url, this page does not load an has always loaded before: http://www.freembb.com/our-team
– With the /, the page now loads. This is a minor problem because my menu link does not contain the / at the end of the url. http://www.freembb.com/our-team/

Any ideas or tips?

Thanks,
