I've been running WP for 5 weeks with no problem and then suddenly overnight I have no access to my admin pages. Clicking on login gives a blank screen at http://wp.macfusion.org/wp-login.php
This is really discouraging because if I have to reinstall it all I still won't know what caused the problem and it can just repeat on any given day. I've done the obvious, turn off the plugins, empty the cache and cookies, reboot, etc. I'm stumped.
