I'd like to thanks you for this nice plugin :)
I am writing because I met some flaws when using latest iThemes Security and WPML. I made little examination and it happens using WordPress 3.8.3, WordPress 3.9 and WPML 3.1.4 and 3.1.5b2.
The flaw concerns redirection of hide backend url, which is redirected by WPML to frontend browser language version of homepage.
I made a ticket on WPML forum as well, describing the problem.

Can you help us with this problem? It's the only issue we have with the plugin.
