I've activated AddThis support with my AddThis username under Site Administration -> API Keys
The AddThis widget appears on every page in the Header Section (Title) of my website. If i configure like i've seen here as example (master.layout and theme.skin), i have TWO of them, on the top as i said and on the left
Yes, the blog has its own widgets. If you don't want both of them then you could either use a different skin on the blog page and remove it from layout.master or just disable it in the blog settings and use only the one in layout.master.
Hope that helps,
The problem is, i think it's not related specific to Blog module. It appears on every page, without exception. I've not altered any layout.master. I've only entered Addthis suport writing my username at Api Keys. I've also enabled 'Hide AddThis...' on Blog module, but it only hides from posts, not from page's header.
The only to do remove it is leaving blank Api Key. I really want to use Addthis at every page, but not on two places. Just on the left, like you've wrote in your article
Right now the only thing I see on your site is the old AddThis button not the new AddThis widget.
To use the new Widget you must update your layout.master file and replace the old button with the new widget.
