 * Hi there
 * I have been using this plugin for a while but since there’s version 3 (I think)
   the site breaks when using the “Autoptimize plugin” with “Optimize CSS Code” 
   enabled.
    The problem is with Optimize CSS Code enabled, it makes a very big 
   difference at Gtmetrix for PageSpeed Score and Yslow score. It took a while to
   locate what was causing the site to break until I came to this plugin setting.
 * Is there anyway to use the zstore plugin without compromising its score and performance?
 * I would very much appreciate your response.
 * Kind regards
