Somehow all my posts automatically add a prefix word 'tweet' in the feeds.
The prefix is viewable on the site in the page source (couple lines after feed autodiscovery tags) of individual stories.
( <meta property="og:description" content="Tweet ... )
I remember I made some changes in SEO>RSS section (content to put in before and after each feed). I tried disabling the plugin as well but still all my feeds add a prefix word 'tweet'.
Any help is highly appreciated.
