I am using the WordPress.com Stats plugin on my blog, but in the wordpress.com dashboard, when I checked my blogs it says that this blog is set to be hidden, and it seem that I can not change that by clicking the link to set is as visible!!
my blog is : http://www.famousbloggers.net
By the way, I have multiple blogs that running the same plugin and it's visible! I am not sure why this one is not.
