I'm unable to share my blogposts to any social bookmarkingsites such as Stumbleupon, nujij.nl etc. It says that the URL does not exist, but the site is reachable and online. I have the feeling that there's some setting configured wrong, but I don't know what it is. I am using a self-hosted wordpress domain/url. Can anyone help me?
The blog I need help with is www.blog.sempermedia-webshop.nl.
