I can't add my site on WordPress showcase. I fill all field and push submit. then I see this message.
We were unable to detect the latest version of WordPress at the given URL. We'd prefer submissions to the showcase to be running up-to-date versions of WordPress.
If you're sure the site is running the latest version of WordPress, then please check the URL to make sure it's accurate, and that the URL you submit points directly to the location where WordPress is running.
But this site is updated to 3.5.1
