Sometimes while installing theme, plugin or accessing a module while developing the website, you may encounter white page. A generic solution to this is to increase the memory allocated to PHP.

If you have access to your PHP.ini file,find “memory_limit” and change the line in PHP.ini to
memory_limit = 64M ;

64 MB will be enough because it is the maximum amount of memory a script may consume.

In case you don’t have access to PHP.ini, try adding this to an .htaccess file
php_value memory_limit 64M

Also try adding this line to your wp-config.php file
Increasing memory allocated to PHP
define(‘WP_MEMORY_LIMIT’, ’64M’);

If that doesn’t help, try resolving this with the help of your host.
