 * I use this plugin for a number of sites, it was wonderful until the update!
 * There is a serious problem with how it interacts with javascript and the mailer.
   Switching to an smtp plugin solved only 1/2 of the problem. The mail now submits
   but the javascript arrows never stop churning, ever!!
 * I am not quite afraid up updating the plugin on my other sites. Please investigate!
 * Please be aware that smaller sites cannot simply turn off all their plugins and
   switch to a generic theme, they lack the resources (people and $) to have a true
   development site. Adding a development site on a shared server often means turning
   on multisite which then has to be uninstalled, rather ripped out, of the server.

 * Miyoshi-san.
 * As I said in my previous message that option is often not feasible for smaller
   sites.
 * Since your software is the only thing that changed (not WP version or the theme)
   did your javascript calls change at all?
 * Kind regards,
 * ELB
