"If you can see the page you are on in the address bar when looking at the blank screen you can use echo statements to find the error. Just open up the page that is blank and then starting from just below the opening &lt;?php mark,  type in several places down the page something like:\n \necho 'line 2'; or echo 'line 50';  \n \nAs long as you haven't placed them within a 'if then' statement, then the echo statements you add above the error will print on the screen and the echo statements below the error will not print, and you can narrow down exactly where the error is.\n"
