Those are typically from what I presume you're using is Internet Explorer not liking the way some of the code is formatted on the website. They can be ignored if you are not having issues with the site. Each browser will complain about something and call it an Error in some way or another. You have to have an extremely basic page to not have a complaint about an error, or one crafted for every web browser out there.

That would need a web developer to remove. If you aren't having issues with the website browsing and functionality-wise, it's nothing to worry about. IE is a little more audible when it comes down to code it doesn't like than other browsers, but every browser is going to "error" unless a site was made for a specific browser.
