It is not just your wikis. Take a look at the home page for Community Central. Something Wikia changed has made it so that the elements contained in the right column are allowed to overflow. I checked on the wiki I admin and we do not have this problem. the only reason is that all our right column content is passed to a template which places it in a div with width:100%;. However, without this, we have the same problem as well. - Edit:

For now, you can remedy the issue by placing the following in your site CSS.
