I have seen this multiple times. It is usually the result on an unclosed tag. This may be caused by tags that you are using directly or by tags that are placed when converting MediaWiki markup (such as tables). It may be due to tags placed directly on the main page or tags placed on templates used on the main page.

I would suggest a thorough review of your main page and the templates transcluded on it. Look for any unclosed tags/tables.
