OG title and description on Facebook

Hello

Can you please tell me where these are defined for the homepage please?
Our homepage is working fine (in preview on Facebook) when shared with https://
but when shared without SSL (with http) it shows your defined tags
Fest - Responsive Event WordPress theme
Frontpage

Thanks in advance for getting back to me!

Hello,
Could you please provide me with a URL to your website, either here or via PM (click the “Private Message” text underneath my avatar) so that I may analyze it? You can also disable Open Graph generated from the Fest theme (Template Options -> Features -> Enable support for Open Graph) then you can use any 3rd party plugin with Open Graph support.
