Could not load cross-domain resources

When my site loads I get thousands of these errors in my browser.

Could not load cross-domain resources: dofo.uacss

I assume the issue is because the site is https and there are resources trying to load that are not https.

Mixed Content: The page at 'xx' was loaded over HTTPS, but requested an insecure script ' ajax.googleapis.com/ajax/libs/dojo/1.5.1/dojo/uacss.xd.js '. This request has been blocked; the content must be served over HTTPS.

Not sure if this is part of OS Property extension or the OS template I am using.

Hi Mark,
The issue comes from Ajax search module, we removed that module out of OS Property for a long time. Please unpublish Ajax search module to solve the issue.
Thanks
