After Install all pages blank

hi installed the sript, but all pages including admin come up blank

http://www.allvideocodecs.com

can anyone help? :(

Whatever page your trying to access, place this code at the VERY TOP of the page.

<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
?>

Save, then upload. Then press F5 to reload the page. Your errors will print to the screen, then you can start debugging.

I had same problem - turned out ffmpeg was not installed properly. See if it is showing on your phpinfo.php page. If it isn't, that is likely your prob.

You need to enable error reporting in PHP to display errors.
