yes, it was the view_downloads.php file.
make sure that you did not incluse any surrounding spaces when copying the line of code I gave you.
Make sure that there is no space at the end of line 1 for example"
"<?php set_time_limit(0); ?> "
also make sure there is not a blank line between the closing php tag "?>" on line 1 and the next opening php tag "<?php", for example:
<?php set_time_limit(0); ?>
