SSL?

It should be compatible already as it doesn’t link to any external resources.

If you are using something like Google Adwords just change the external link to reference the show_ads.js over https instead of http using the below link.

I had the same issue and changing the reference to show_ads.js over https resolved the issue.

Hope that helps.
