I’m afraid this not what I’m needing. What you’ve sent is the Apache log (which logs every request to the server), and what we need to look into is the PHP error log.
This tutorial on How to view error logs in cPanel might be useful. If you are not sure about it you can reach out to your hosting provider and ask them for it. We are trying to see if the code (blank page) is due to a PHP (code) error, and if true then in which file and line is the error generating.
You can also add this line to your wp-config.php file (as explained here):
define( 'WP_DEBUG', true );
To make the error visible on the admin (it should show an error description in the blank page). Although this might not work depending your server settings.
Thanks,
