I visited your site but I get a default page saying the site isn’t available yet.
What I can say for now is make sure you have properly configured the theme to use the one-page template.
Go to Appearance > Setup Parallel and follow the instructions.
The header and menu should work properly when that is completed.
You can edit the footer text and add links by going to the Footer/Credits section in the Parallel Options Panel in your Admin Dashboard.
Let me know if you have any issues.
