Hi Im having the same issue.
Not sure what happened but i resintalled my site, now stretch and full width dont work. top image is meant to stretch all the way http://geniustudios.com/index.php/print-portfolio/
Ive spoken to the plugin dev’s they said its to do with the theme and to speak to you. Heres what theyve said:
From the looks of things, this is the error that’s causing the problem:
shapely-scripts.js?ver=20160115:139 Uncaught TypeError: $(…).flexslider is not a function
That script is part of your theme, Shapely. If you contact the theme developers, they might be able to help.
