 * Need some help please… I’m having major resource usage issues. My host (Inmotion
   Hosting) advised that the admin-ajax.php file is the culprit and provided some
   instructions (disable heartbeat + cron job, remove resource hungry plugins and
   implement caching) on how to fix it.
 * I did everything they recommended but I’m still having issues. My current setup
   now:
 * – Plugins: WordPress SEO (tried Meta Tag Adder and no plugin), Ultimate Social
   Deux (tried Simple Social Buttons Plus), WP Rocket (tried W3, Super and WP Fastest
   Cache Premium), and Heartbeat Control
 * – Theme: Milk-It from Theme Forest (tried Genesis Framework and Thesis 2.0)
 * – CDN: Using both MaxCDN and CloudFlare (tried no CDN, Cloudflare Only and MaxCDN
   only)
 * – Sql database – has the original 11 tables and is cleaner than a monkey’s butt(
   no options and transients left over from old plugins/themes)
 * You name it, I’ve done it. I’ve spent the past month trying to figure it out.
   Can anyone help me with this?
 * Thank you so much
 * Below are the numbers from today from the usage stats:
    1 134139 23.43% 55753
   1.54% /wp-admin/admin-ajax.php
 * I’m currently using the latest version of WordPress

 * Remove the social share sharing plugin and replace your current caching plugin
   with WP Fastest Cache plugin (free). That should fix it.
