I followed the directions for how to setup SM for changing passwords and I end up with a blank page. I have turned error logging on and am having it log to /var/log/php-scripts.log file and nothing shows up in there. I am totally confused as what to do. If anyone here has any ideas please let me know as I dont know where to start.

/var/log/php-scripts.log shouldn't be writable by the vu2000 user wich runs squirrelmail so this may be a permission problem. Try enabling display_errors and display_startup_errors in /var/www/fcgid/master/php{VERSION}/php.ini so you can easily fix the problem and then turn them off again.
