I have a site, familyfarmhealth.com when you click on any of the navigations the resulting page is always the home page, even though when you mouse over the navigation link it shows the correct URL.
At first I though it might of been caused by a Plugin, I deactivated all plugins one by one and this behavior continues.
Then I thought maybe it is a browser caching problem, although I have tried viewing the site in Firefox, Chrome, IE all with same results.
Since the site had a custom theme installed, I loaded up a random theme from WordPress.org to see if that might be the problem. No changed (other than the random theme isnt using Apperance > Menus as with the custom theme)
Back to the browser caching issue, I then attempted to view the site via a proxy site, http://www.anonymouse.org and same issue.
It appears that this might be an issue directly with WordPress, unless I missed something.
NOTE: I do NOT have any WordPress caching plugins installed nor has there been any install.
I am stumped on this one, any ideas or help is appreciated!
