ok, i installed php/apache/mysql a couple of weeks ago, and it took a couple tries, but eventually, i got it all to work, and it read this php file i had made. now, a couple weeks later, i open the same file in ie, and the part in the php tags is blank....it wont read it. i hadnt done anything to any of the files too. i tried playing with some http.conf and the php config file, but that doesnt do anything....what do i do?
