Facebook sending users an unsecured message on shares

[Dave_Nation_n_a]

I'm hoping someone may have had this experience previously and can provide some insight to help us out. We have an alias microsite LP go.totallylocal.nz when users attempt to share this page in FB, they receive the following message:

It is a secured domain so I don't understand why FB would be seeing it as unsecured. Has anyone else had this issue?

The link in the warning is rdg.co.nz, not go.totallylocal.nz.

Make sure you don't have any broken asset URLs on go.totallylocal.nz that are redirecting to the plain-text (http://) version of rdg.co.nz.

This can include favicons and other assets you may not deem important, but which cause a page to be seen as insecure due to mixed content.
