we checked your site and looks like you have JS errors what is not related with theme. Just look at http://pasteboard.co/o7DjMWk.png and see what we mean. In such case, we recommend to deactivate all plugins. But if this won't help, you must re-install all files via FTP (wordpress, theme, plugins) because your files may be corrupted while migration.

Thanks!
solved by going to the Settings/ Permalinks section
And pushing the save settings.
It often happens because of the .htaccess havent been updated or moved over
