Hi Bojan,
You are correct that all other pages are working just fine in http and https it is only the virtual pages that are in question and only if you call them directly. This is a major problem since it would render any login page useless.
I do not see how it could be an issue with the SSL setup as it works properly on the rest of our wordpress and application site without fail.
As I mentioned I did find another article mentioning clearing the permalinks by saving them and I have already tried that.
