Theme Issue

the inner page has validation errors http://validator.w3.org/check?uri=http%3A%2F%2Fthyrominetim.com%2Fthyromine-reviews%2F&charset=%28detect+automatically%29&doctype=Inline&group=0

as comparison the error report from the front page: http://validator.w3.org/check?uri=http%3A%2F%2Fthyrominetim.com%2F&charset=%28detect+automatically%29&doctype=Inline&group=0

these errors with ‘end tag for element “div” which is not open ‘ point to some unmatched opening/closing html tags within the templates of your theme or in the content of the page/post with the problem.

try to fix these errors – http://codex.wordpress.org/Validating_a_Website

however, the main cause seems to be this section in the template of the inner page (page.php if it is a static page; single.php if it is a post)

<!--postwrap -->
  <div class="postwrap" style="width:917px;">
    <div class="clearer"></div>

remove or change the style="width:917px;" part.

the same section from the front page:

<!--postwrap -->
  <div class="postwrap" style="width:667px;">
    <div class="clearer"></div>
