Wordpress/Webmaster Errors

I keep getting errors in Google Webmasters. they are function.implode and things along this nature. Anyone else having this issues? If you are having this issue how did you fix it? Could it just be an issue with my theme?

After looking through it more I found that it has several other errors that have function.(somethinghere) but when I search through the code of the theme I can't find this anywhere.

Any thoughts?
