simonacampidano on "Problem with Twitter sharing"

Hi!

I have a problem with the sharing Twitter button at the end of my posts. Once anyone clicks on it, it opens a new window saying "XXXXX via @Zimo1984". The problem is that I changed my Twitter name, so I want it to be "via @SimonaCampidano" instead, but even if I go to settings->sharing, and I insert the new Twitter name under "Twitter username to include in tweets when people share using the Twitter button.", it does not change it when I try to share the post.

Does anyone know how I can solve this problem?

Thanks a lot!
