How to correct duplicate Title Tags, Meta Keywords, Meta Description

My website returns duplicate Title Tags, Meta Keywords and Meta Description when you view the source code: http://www.learningenglish.uk.com

I use the plugin WP SEO by YOAST

Error: The required Title Tag found in this document is "not correct". We found duplicate Title Tags in this document which is not allowed
Error: We found duplicate Meta Description Tags in this document which is not allowed.
Error: We found duplicate Meta Keywords Tags in this document which is not allowed.

How can I correct these?

Thanks.

May be it is just because of you putted meta from your theme option also.
Thanks & Regards
