Create New Post Error post-2.6.5 upgrade, browser error

Hi,

I recently upgraded to 2.6.5 for two sites, one site is working perfectly and this other is experiencing some minor glitches. When I login in to the admin panel using Internet Explorer and then go to write a new post, I receive an error that reads:

“Internet Explorer cannot open the internet site https://globalethics.org/newsline/wp-admin/post-new.php.

Operation aborted.”

I do not however have this error in Firefox. Is there a quick remedy for this error?

Thanks.
