 * In the beginning when I installed the plugin everything worked fine. After a 
   time I got “undefined”. Everytime I want to login, I got this error. No matter
   what user, right or wrong password. WHY? 🙁

 * same here, not sure what is causing it ? the big problem is they have removed
   the login from woo 2 so we need this, without it woocommerce is not much use

 * Same problem here. I deactivated the plugin and went back to using the meta widget.
   I’ll wait until they fix this. I was able to login through the /wp-login.php 
   link

 * I am also experienced “Undefined” in red above the login screen, when nothing
   is at all wrong with the login credentials.

 * The problem may be related to caching again because I suddenly received the error
   after installing w3-total-cache. Also, I noticed that if I refresh the page, 
   try to login again, and refresh the page again, all is well.
 * I have the widget displaying on only one page that is not the home page. Excluding
   that one page from caching seems to help, but after successfully logging in (
   and not seeing “undefined”), a page refresh is still required.

 * It’s not related to caching because I don’t use any caching plugins.

 * I got this “undefined” message a day or two ago – obviously after installing 
   the update, which is a rewrite (as the author stated). After downgrading to 2.5.0
   again everything works fine again.

 * Perhaps for the developer a idea to display the return results next to the undefined
   message. So people can return the debug info.
