Very handy debug tool
wp-config.php file special options that will let it tell you more:
define('WP_DEBUG', true); //Will also track PHP Warnings and Notices to make them easier to find.
define('SAVEQUERIES', true); //mysql queries are tracked and displayed.Feel free to comment if you can add help to this page or point out issues and solutions you have found. I do not provide support on this site, if you need help with a problem head over to stack overflow.
