Hello, @Oliver Theiß,
Sorry to say, I don’t know why the plugin support doesn’t reply back to you usually, support takes 48 hours to reply but it’s been a very long now. Please try to contact them again I hope soon they will reply back to your query. Making the plugin compatible with our theme requires huge customization If you want paid Customization services to submit a customization request to WPKraken team.
This is something beyond our limitations.
I hope you can understand.
Regards 8Themes Team.
