Logo image rendering without https://

Hi,

Thank you for this amazing theme. We just started using it on a new website when we noticed that chrome was reporting that some of the images are not secure. On looking at the source we realized that even though the site is ssl enabled and all other images render with https, the log renders with an http for some reason.

Could you please help?

Thanks
