Output doesn't update

[iamgaurav]

I am being using Prestashop for a while and developed a few modules. Some of them require crons to run so i have simply made a cron.php file which has prestashop config included and i run that to update my DB. But from the past 2 days none of these cron's are working i just keep a blank page without any error or when i create a new php file the first output which i get from that file thats the end the output will not change even if i change the code etc. I disabled xcache which i was using earlier still everything is the same.

Any solution for this ?

white page = errors

turn on error reporting and we will see where the problem is (i hope so)
