 * Dear Support,
 * I am contacting you because since last December (5 months ago) I have discovered
   that Shield Security is not compatible with SG Optmizer, a very famous and mandatory
   plugin for websites hosted by SG.
 * Your plugin requests users to disable important features part of SG Optimizer.
   I hoped that this was just a brief temporarily solution.
    Did you manage to solve
   the compatibility issues of Shield Security? Is there a way I can still keep 
   using Shield Security without disabling features (Defer Render-blocking JS, and
   Remove Query Strings From Static Resources) of SG Optimizer?
 * Thanks for your support.
 * F.

 * Unfortunately not.
 * It doesn’t matter how “famous” a plugin is. If its “features” break things, then
   we can’t be compatible with it.
 * The features actually don’t make much sense. Sure, the **principles** upon which
   they operate are sound. But there’s **no** way that a general-use plugin can 
   possibly accurately determine which JS can, without errors, be deferred. This
   should be done on a per-script basis, and with testing.
 * Most people don’t test, however. They see a checkbox that implies “make my site
   faster”, and they just check it.
 * Equally, the plugin cannot accurately determine which resources should be static.
   So it breaks caching rules by making everything static. And again, people check
   these boxes without due diligence and then we see people’s sites break because“
   Shield has a bug”, which it doesn’t.
 * Providing support because a plugin’s “features” break the site is not viable.
 * To understand more about optimisation on a site, please read here, particularly
   the 1st rule.

 * I’m sorry if this isn’t what you want to hear, but thanks for checking with us.
 * We’ll review the settings again and see if the incompatibilities still apply.
