I have try every possible solution to solve the strange behavior of your plugin on my site.
When typing first password,every character is displayed at second row below password field.
I can not type a second password in repeat field.
See and test it: http://www.mijnmemorandum.nl/nl/test/
I am strugling now for 4 days getting a solution.
I am not happy with this plugin for more 80 USD.
