Hi,
The white page means some problem in PHP code. Please, enable the error reporting on your server, so there is an error reported instead of just the white page, and post the error message text.
There are several ways to enable error reporting:
1. The easiest, in Joomla's Global configuration on Server tab set Error reporting to Maximum. However, this option doesn't always work.
2. By adding the following lines to the beginning of your .htaccess file:
php_flag display_errors on
php_value error_reporting 7
This option usually works.
3. Enable error reporting in Apache server's configuration - you usually need to contact your web host to do this.
If you have access to your server's error logs, you can also find the error message there, so you don't need to enable error reporting on your website.
Best regards,
