FOR THOSE OF YOU WHO ARE LOOKING FOR A SOLUTION TO WORDBOOKER RE-POSTING PREVIOUS OR AGED BLOG POSTINGS TO YOUR FB PAGE (AFTER PERFORMING ANY TYPE OF EDIT), THIS IS WHAT YOU DO TO PREVENT IT.
Go to > Settings > Wordbooker
Scroll down until you see the line that says: Update Facebook Status (followed by a check box) and then a text box with some pre input writing about Title and Post with a % symbol. Erase what you have in that text box. It should be blank. Save it.
Doing this has prevented all of the re-posts upon edit for my blog and it’s feed to my FB page.
Hope this helps.
