I posted the same type of problem on here:
I have a twitter feed plugin installed. When I activate the WordPress SEO (version 1.4.7), my twitter feeds double on the username (see bold portion of example):
LONESTAR Sets Tuesday, June 4 Release Date For 'Life As We Know It' | Music News NashvilleMusic News Nashville http://www.musicnewsnashville.com/lonestar-sets-tuesday-june-4-release-date-for-life-as-we-know-it
I cannot find anything in the plugin to address this issue.
Suggestions?
None of these solutions are working
