UPDATE: This plugin is updated already, no need to download this fix. Just download the latest copy on the WordPress Plugins site.
If you upgraded to WordPress 2.7. And you are also using the SEO Title Tag plugin by Stephan Spencer, you may notice that the tabs on the “thin slicing” view (The view where you enter all the title tags of various pages on a single page, I learn the term “Thin Slicing” from Stephan Spencer himself when he talked about the plugin in a session at Pubcon), you cannot choose the other tabs.
The default tab is Pages, and even if you click on the other tabs, nothing happens. The fastest fix I found is simply modify all files of the plugin and replace all occurences of edit.php and change it to tools.php then reupload the file and you are all set.
I am sure an official update will come soon. but if you can’t wait for the update, and you are also not confident with your coding skills to touch anything, you can download a modified version here. I’ll ping this over to Stephan on his twitter so the update comes sooner hopefully. It is not a hard fix anyway, i’m sure the official update will come very soon.
