In a Drupal site, I've a hashtag appended to my url. Example:
www.myUrl.com/content/node#.UFnCybLN9Nu
I don't know where it comes from and I don't know how to remove it. Any ideas?
That is coming from the AddThis service (media sharing icons). You maybe copied a link from there or if you are using that module, you selected to track the shared links.
If it's your widget, you can disable it by removing a line in JS (there is something like "track = true"
in the widget code).
