Hello,
The blank white screen is caused in most cases by poor ssl implementation. Most likely your site url is not the same as the home url. After you make the move to ssl, please make sure these 2 boxes show the same link with https in front: https://www.screencast.com/t/ouiuuHe7UaNh
The system status screen will usually let you know about this: https://www.screencast.com/t/rFGJQ7woAb
Thank you!
This happens when creating 2 topics with the same issue. I got to your other topic before I saw this one so I could not have know you already checked for this issue.
If you still need us to login and investigate please contact us on our email address at contact@tagdiv.com and provide a link to your site and wp-admin (login information and admin rights) so we can login and investigate. Please also include a link to this conversation.
Thank you!
