I have been doing tests for errors on the iPhone. And kept getting an output relating to Facebook.
Javascript Warning on Line 56
h**p://connect.facebook…t/en_US/all.js#xfbml=1
FB.getLoginStatus() called before calling FB.init().
So to sort it out I changed the line in the ‘simple-social-buttons.php’ file…
js.src = "//connect.facebook.net/<?php echo $lang_fb; ?>/all.js#xfbml=1";
to…
js.src = "//connect.facebook.net/<?php echo $lang_fb; ?>/all.js#xfbml=1&status=0";
