I presume you do infact have a SSL cert. installed? My site is working fine with Internet Explorer, which IE are you using?
For my website I have a page with video content which is insecure but I wanted the rest of the site to be secure.
Let's say my website is http://www.example.com and my page I want to be http is http://www.example.com/livestream/
The settings I use in wordpress-https are:
SSL Host: example.com
Force SSL Administration: Checked
Force SSL Exclusively: Checked
Then in the Secure filters box I have only the following:
And that is it.
One more thing I have thought of is you may have the settings the same as above or setup correctly, but you may have the page's parent the page which you want http, setup to force ssl manually.
So make sure you check that the page doesn't have "secure post" checked or the page's parent does not have "secure child posts" checked. (These options can be found in the wordpress edit page admin panel)
