a complete blank page indication of php error while php error reporting switched off.

to see real error, you've switch on using 1 of these methods:

in back-end go to: system > global configuration > [server] tab >
change "error reporting" "system default" "maximum"

or can add following code .htaccess override server settings , show php errors:

code: select all

php_flag display_errors on
php_value error_reporting -1
