I’ve followed the instructions on https://theme.co/docs/product-validation#validating-development-areas for validating X on a staging site, and I’ve added the staging site URL to the licence page. However, when I add the licence number to the validation screen on the staging site, I get redirected to https://staging.mysite.co.uk/wp-admin/admin.php? which is a blank page. When I go back to the validation page, X is still unvalidated.
What am I doing wrong?
