I'm running WordPress 2.0.5 and have an SSL certificate available. I installed the Secure Admin plugin this morning, visited my admin, activated the plugin, and ran into a brick wall.
Although I can login to the admin now (which *is* using the SSL certificate), any time I try to navigate away from the dashboard, such as to view my profile, add a post, etc., I get the following error message:
You do not have sufficient permissions to access this page.
The HTTP response code is 200, not 302, so it looks like there's some sort of WordPress authentication issue.
The user I'm logged in as IS an administrator (actually there *is* only one user) so that wouldn't seem to be the problem.
All my file permissions are set to 644. I tried setting the admin file permissions to 755 but that didn't help anything so I bumped them back down.
This issue seems to be something that other people have run into, but I haven't seen a solution. I like the idea of using this plugin instead of the other SSL-on-Admin ideas that I've seen posted around, but obviously I can't use it if I can't make it work! ;)
