After I paste the code to my site index page, the buttons are not visible.
Only the text: Share on facebook Share on twitter Share on print Share on hyves More Sharing Services are visible on my site now.
What I am doing wrong?
You're probably viewing your pages by opening them as local files rather than loading them from a web server. So instead of the URL of the page in your browser starting with http:// it starts with C:\ or file://
Here's what the AddThis buttons look like when viewed via http:// - http://i.imgur.com/IDGUD.png
And here's the same file viewed using file:// - http://i.imgur.com/gpCco.png
I've submitted a ticket to our developers to fix this for people previewing pages using their file system rather than a web server, but until they can get that implemented you should either understand that the buttons won't show up if using the file:// protocol or use a web server in order to test how your sites display in browsers.
