 * Hello
 * After updating to v3.5 I am experiencing 406, Mod Security errors on all 15 plug-
   ins I have installed when I click on edit. The error message reads as follows:
 * Error 406 – Not Acceptable
 * An error has occurred. Generally a 406 error is caused because a request has 
   been blocked by Mod Security. If you believe that your request has been blocked
   by mistake please contact the web site owner.
 * All my plugins are up to date, I have deactivated all plug-ins and then re-activated
   each individually, run diagnostics which show everything is ok and there is no
   reason I should be receiving this error.
 * I have also contacted my hosting company who have advised me this is actually
   a software bug that will require a permanent fix by either WordPress or Mod Security.
 * (My site is currently in maintenance mode and not live so I have not provided
   a link to it.)
