I just installed WordPress 3.1.3 for one site. The visual editor, however, does not appear when I access it in either Safari 5.0.5 or Firefox 5.0 on a Mac running OS 10.6.8. I have no plugins installed.
I am using WooTheme's VibrantCMS. I have the same theme installed on another WordPress site that's also running 3.1.3, however, and the visual editor loads correctly.
Thanks for any help you can provide!
