If you have the Really Simple SSL Pro installed, you might get the warning that your site contains a reference to an external resources that cannot load over SSL.
If you see a domain looking like this one: “http://i0.wp.com”, you have a JetPack plugin, Photon, installed. Deactivate it, and this issue should be resolved.
If this file is from a service you are using, it’s best to contact them and ask if the service can be provided over SSL as well, as it should in my opinion. If that is not possible, you can try the steps below. Please take care not to violate any intellectual property rights. Ask permission to use files on your own server before you do.
An example: if a page contains this html:
And that domain does not have an SSL certificate, this image won’t load on SSL.
To fix this you should:
- Download the file on your computer (please take care not to violate intellectual property rights, contact the owner if necessary)
- Upload it in your website with Filezilla, for example to wp-content/uploads
- Change the url to your own domain, for example to www.domain.com/wp-content/uploads/yourfile.jpg
Or you can of course choose to remove the image.
If this is a .css file or a .js file, you can try this as well, but it may depend on local resources to work. If that is the case, downloading the file will break the dependencies.
Sometimes the domain gmpg.org pops up in these results. You can ignore this domain: it’s harmless.
