Always redirect based on GeoLocation/ Comment Functionality broken

Hi there
first of all, thank you for the great work on your plugin, works pretty good so far.

But i ran into a problem: My site redirects users from switzerland to /ch and users from germany to /de and the rest gets on the english page. I am also using WPML to have content for the different languages. Now when i try to access a english blog post from siwtzerland i will be redirected to the swiss content (which works good) but here the comment function is broken, because it redirects the /wp-comments-post.php link to /ch/wp-comments-post.php
How can i prevent this?
