Drupal site does not show well when SSL is enabled
You get this message from MSIE because the page has a mixture of secure and insecure content.

The culprit is usually inline/embedded content (images, iframes, javascript, css, etc.) that originate from a non-secure URL. Chrome just refuses to load it, causing the error you see To fix it, you need to locate those elements of the page, and replace them with secure versions.

To locate for these elements of the markup (unless they are obvious now that you know what to look for), use FireBug (requires that you use FireFox instead of MSIE/Chrome) or just press CTRL+uin MSIE to analyze the markup.  In the markup, search for inline/embedded content hyperlinked with URLs starting with http: (instead of https:).

If all your links are internal (i.e. pointing to stuff below the webroot of the same server), you can eliminate the problem by dropping the scheme element of the URL (as suggested in a comment below by @JohnathanElmore).

In other words: if your server is example.com and you currently have the following URL reference as part of your theme:

src="http://example.com/sites/all/modules/spamspan/spamspan.js?somequerystring"


you should replace it with the following:

src="//example.com/sites/all/modules/spamspan/spamspan.js?somequerystring"


or even:

src="/sites/all/modules/spamspan/spamspan.js?somequerystring"


I can't tell you exactly how to go about making these replacements without knowing what you can and cannot do on your site. (If it was my site, I would simply edit the theme templates and clear alll caches. But I've no way of knowing whether this option is available to you.)
