Re: V5.0 to V5.1 problem
Emmett, looking at your site with Firefox and the Firebug add-on (CSS inspector), I see that at the top of your wikitext there is a div with these properties: margin-left: auto; margin-right: auto; width: 2px. This div is apparently made in the wikitext. If you change the width to the same as that of the image (600px), the page seems to display OK.
No ideas yet about the left column.
