the_content returns blank when adding SEO details

I am using the Thesis theme and wanted a custom style for my pages. So I created a custom template while using thesis hooks and functions where applicable. I am doing this with a solution similar to the method described here so other contributors can use the themes in their pages as well.

I am getting the post's content by using the function the_content().

While this works normally and returns the contents of the pages, if I specify the SEO details (meta title, keywords, description etc), the_content() returns a blank.

Why should adding meta details to a page affect the_content like this? Would appreciate if someone can help me out with this.

Thanks.
