If you recently upgraded to WordPress 3 and you’re using their new default Theme together with the famous All in One SEO Pack Plugin, you probably already noticed an annoying little bug: Your blog title is now appearing twice. Kinda defeats the whole SEO thing…
While the bug itself hasn’t been fixed yet, there’s a simple workaround.
Open up functions.php of your TwentyTen theme and go to line 262.
You’ll see a line that looks like
add_filter( 'wp_title', 'twentyten_filter_wp_title', 10, 2 );
Just add two forward slashes in front of it so that it looks like
//add_filter( 'wp_title', 'twentyten_filter_wp_title', 10, 2 );
Everything looks like it’s supposed to and AIOSEOP is back to doing its magic.
