The 'Dreaded Blank White Screen' appears when saving or updating in WP?

Im trying to trouble shoot the "blank white screen" which appears when I try to save or update in wp. To get out of it, I have to use the back arrow. I know I have an error somewhere in my code in a template file somewhere. I think the problem appeared midway in the 'Creating A Portfolio Single Page ' lesson, maybe after I added the custom post type and custom field.

Most of the time when this happens to me it is a missing semi-colon in some line of PHP. I would got back into the file that you edited most recently and save each time you hit Undo. After each time make sure to refresh the browser to pinpoint which change caused the white screen to appear.

Too many files to scour the code, so I got lazy and replaced my functions.php file with the course download functions.php, and it fixed the problem. I must have had a semi colon out of place somewhere in there.
