This error is related to CB Login and the registration page. I have enabled SSL in the login module, but the Facebook and Twitter images do not show up when in SSL mode in IE. I am using CB Addons. IE pops up the error saying page contains secure and non secure items. This also happens in the registration page. Al images are not visible when I say 'Yes' to the IE error - show on secure items. That tells me the images url is not HTTPS. Non of the image have any HTTP or HTTPs on them. They are all /images/... so the url should be created correctly.
