federicom985 on "[Plugin: WordPress SEO by Yoast] error on line 2 at column 1: Extra content at the end of the docume"

Hi, i add to my previous comment: I am using WPML version 2.6.1 (last version) and I am running 2 languages. I am using Wordpress SEO because it should work fine with WPML, creating sitemaps per languages.

If I hide the 2nd language in WPML I don't have the error, while if I enable the 2nd language, there is this error. I don't have any idea to solve alone..Please Help!!

Thanks!
