Why does it keep displaying br tags and claiming 404 errors on like 4 of my URL's for all my Wordpress sites?

Is anyone else having the same issue? These errors don't actually exist and i think it has something to do with wordpress - how can i fix this?

Have you visited the pages in question and viewed the response headers? It's strange, but sometimes a web server can serve up a page but still put out a 404 in the header. And with CMS driven sites like Wordpress (without physical page files), it's easy to create a 404 URL by simply linking to a typo.

So i took a look at our SEOMOZ Pro account - it's showing me 4 URL's similar to the one below:

404 : Error

http://dfwsinusselect.com/about-balloon-sinuplasty/insurance/<br

However, nowhere in my site can I find any links with %3Cbr (which is basically the
tag.

Without that ending, the URL works fine, and that's how it is linked throughout the site... so I guess what I'm saying is that I'm having this very issue with multiple Wordpress sites.
