[Plugin: SimpleModal Login] empty_both error

Hey,

I am getting with empty_both error and lag when testing with an incorrect username/password. I have noticed the script error;

Uncaught TypeError: Cannot read property ‘data’ of undefined
SimpleModalLogin.show
SimpleModalLogin.init
f.event.dispatch

Is there a fix for this?

Thanks
