I just got back after a week. I still see the blank page when validating.
I added secure note. Please validate my license.
Please kindly enable the WordPress to debug mode so that instead of the blank page it actually shows the error to be able to find out what is the problem:
I suggest that you contact your hosting service provider to get help with the case. And share with them the article below:
Hi, debug mode is on. I tried editing one of the wordpress pages to show errors and it shows the php error. It's just that on the activation page, it shows blank and no errors at all.
I entered your license and your site's now validated (see Secure Note)
