Perhaps if you show us your code… If you’re certain that PHP is running okay, then it must be your script.

Do you have any error reporting on? A blank page can often be an error in the script. Check the error log file.

5

no there is no error log my site is http://funapp.megsta.com

Do you have any error reporting?

No i don’t have

That is your problem, you need error reporting to know what is going wrong in your php script.
