comments only shows a cut page

hi, i'm using your gamezone theme.

when i build links to comments with url/#comments or with the widgets "Comments with Avatars", i only get a cut page. same after writing and submitting a new comment.

normally the page should navigate to the comments-section, if it includes the <div id=comments>-tag.

so here it moves to the section, but the rest of the page above isn't shown. same affects the sidebars. all content is missing or cut.

i've tested some standard themes. the #comments works and only navigate to the comment-section, all content above is shown too.

any idea what could be the reason of this problem?
