If you mean on the settings page for WordPress SEO, that the tabs do not work and you are not able to alter any of the settings within the plugin.
What I suggest you do is install Web Developer Toolbar (on Firefox or similar) and use that to prevent the use of the plugins CSS file. Then all the formatting for the tabs will not load and you’ll be presented with an entire page of options to edit without having to use the tabs.
Then when you’ve finished, remember to enable the CSS for the plugin again.
