 * Recently I was adviced by my hosting service that my site was generating problems
   to the server and they provided me this log:
 * Time: Sat Nov 21 17:40:44 2015 -0500
    Path: ‘/home/******/public_html/wp-content/
   plugins/custom-post-type-ui/js’ Count: 101 emails sent

 * I cant provide the version that was causing this problem since my customer decided
   to update plugins without asking me.
 * The hosting provider decided to disable my site until I fix that. I updated everything
   to the latest version, should I do something else? Is it a known error?
 * Thanks!

 * I am honestly not sure what’s going on here, as CPTUI doesn’t do anything with
   emailing anything or anyone, at least not officially. It’s possible the files
   were modified afterwards by someone/something malicious.
 * Should be safe to re-install the plugin safely, if necessary. You won’t lose 
   content/settings you have already created.
