SuiteCRM 7.6 generating blank pdf


I installed suitecrm 7.6 in our server. Everything is going well except Generating PDF, which gives me a blank page. Searched so many forums but couldn’t find any solution. Please help

PHP Version 5.5.35

Mysql - 5.0

you must give PHP ERROR LOG and in php.ini the PHP ERROR LEVEL.
If NOTICE is enable, you can have this error.
I have make my own pdf function, and i disable in the script with: int error_reporting ([ int $level ] )
