Hi, open the 3-bar menu > Options > Privacy & Security, then under Content Blocking, remove all blocks; also under Permissions, deselect any block on Pop-up windows. Now reload the site. If that works, should you wish, you can make an exception for the site.

If the above doesn't help, also under Permissions, try deselecting 'Prevent accessibility services from accessing your browser,' then reload.
