I have a self-hosted WP blog at http://tammyjrizzo.poppycockpublishing.com,running WP3.5.1, with the following plug-ins active (and all up to date):
Editorial Assistant by Zemanta
Jetpack by WordPress.com
Standard Widget Extensions
UpdraftPlus - Backup/Restore
I have linked Jetpack to publicize my posts on my Facebook, Twitter, Linked-In, Tumblr and Yahoo! accounts. On Facebook and Twitter, at least, all of my posts are publicized three times, and each time it's using a different format. I'm not sure why this is happening, if it's something from WordPress or one of the plugins, or if it's some settings in my social networks, which are all linked together. I've looked at Hootsuite (logged in there) for sharing permissions, and haven't found anything I can recognize as sending blog links to social networks. I've looked at Twitter apps, and haven't found anything I recognize as doing that, either. Same again with Facebook. I'm at a loss as to where to look for the settings causing this triplication of posts. If anyone has any ideas on where I should look, I'd really appreciate your help!
