You only need this patch if you are using the 'WordPress SEO by Yoast' plugin. This will correct an issue where the page title may show up duplicated.

edit bfa_meta_tags.php and change line 12 from

	if(class_exists('seo_ultimate') OR

to

	if(class_exists('seo_ultimate') OR

	// if "WP SEO" Plugin  is installed
	 defined('WPSEO_PATH') OR

or unzip the attached file and upload it to your 'atahualpa/functions' folder

I think I had the same problem your talking about after installing Wordpress SEO by Yoast.

I just checked the box marked "Force rewrite titles"

This is where is says:
"WordPress SEO has auto-detected whether it needs to force rewrite the titles for your pages, if you think it's wrong and you know what you're doing, you can change the setting here."

This is under the Titles and Metas tab for the plugin.

I hope this also helps with this issue.

Some people have reported that worked, it didn't for me or the person who reported the issue and this patch fixed it...
