Hey guys, I got a problem that my Twitter Sharing Button isn't working as I want. In the past, I had the username @bengalow on Twitter. A while ago, I changed it to @grumbeerstambes, but in my WordPress blog, the old name still appears if users want to share my articles (e.g. "We don't like mondays! Fünfjahresauswertung (2008-2013): http://wp.me/p2fzwc-du via @bengalow"). What do I have to do that the new one appears? I already re-add the Twitter-connection at Settings=>Sharing in the Dashboard and at Gravatar.com, but nothing helped. How do I solve this problem?
The blog I need help with is grumbeerstambes.wordpress.com.
