Domain search/transfer page not working

After a plan is selected, the site takes the user to a domain page where they can choose a new domain, to transfer a domain, or use an existing domain.

No matter what option chosen, when the “check”, “transfer” or “use” button is clicked, a “verifying” shows up and the continue button is disabled…and that’s as far as it gets.

I’ve checked with the theme developer and they looked into it and said it was the WP Bridge plugin.

Could you check into this please? I’m tired of manually registering clients.
