Odd 404 errors for a Wordpress site

[burgsimpson]

Hi all,

I'm a designer/developer/web manager for a law firm.

One of our blogs is throwing a lot of 404 errors. The blog is: http://malpractice.burgsimpson.com.

Here's a screenshot from inside Webmaster Tools:

Notice the '-#.html' that's getting added to the end of URLs and causing the crawl errors.

Have any of you seen this before?

Do you have any guesses as to why it's happening? Any template files or plugins you think I should look into?

It works fine for me.

Thanks Steve...

The site does work fine - so why am I getting those 404 errors in Webmaster Tools?

Any ideas?

FYI - the way it works is that every time a user/bot attempts to visit one of those URLs with the '-#.html' attached, and the page doesn't exist, I will get a 404 crawl error in Webmaster Tools.

In other words, the question here is what is appending the '-#.html' at the end of regular, functioning URLs, and causing these errors?
