Breaking styles and breaking last page

Hi,

We’ve purchased your page links plus and auto pagination plugins.

When we enable them, there are two issues:

Issue #1: Breaking last page
The last page of each blog post appears to have a bunch of unclosed tags that are part of our template.

See page 4: http://wwwdev1.pythian.com/blog/concrete-advice-for-abstract-writers/4/
Page 5 (last, broken page): http://wwwdev1.pythian.com/blog/concrete-advice-for-abstract-writers/5/
W3C Validation of page 5 (many errors): http://validator.w3.org/check?uri=http%3A%2F%2Fwwwdev1.pythian.com%2Fblog%2Fconcrete-advice-for-abstract-writers%2F5%2F&charset=%28detect+automatically%29&doctype=Inline&group=0

Issue #2: Splitting pages between open tags
The plugin will split the page up at weird times. For example on this page:

http://wwwdev1.pythian.com/blog/smb-file-share-and-sql-server-an-option-to-consider/

On the first page there is an opening strong tag, and the the page splits after that. Then on the second page there is some text that should be bold, but then is followed by a closing strong tag.

The end result is the rest of the first page after the text is bolded, and the actual text that should be bolded on the second page is not bolded.

Are we using the plugin wrong? What do we have to do to get it to work? Overall the concept is great, but how do we get around these two issues?

Thanks in advance for your help,

John Rau
