I am sorry for the delay of this reply. This is most likely caused by one of the Rok plugins which actually returns a "true" in one of their plugins. Can you please provide me with the back end and FTP access to check on this for you?
I believe I have replied to you on your ticket but in case other users who are wondering why, the problem is actually coming from the content plugin called 'RokSocialButtons'. It is returning a boolean value which causes it to be "1". A quick fix for this is to replace the following codes that you find in the file /plugins/content/roksocialbuttons/roksocialbuttons.php
I have already reported this to Rockettheme and they'll be releasing a fix.
