Yes, I have real CSS (&JavaScript/AJAX/jQuery) errors so checking the CSS and repairing is important. have no idea if the errors from Addthis are contributing to the problems I experience, but if not, its difficult to find the real errors with this huge list using http://validator.w3.org :

Tested and both XHTML and CSS validate without any errors. I don't think these errors are caused by addthis module.
