This ticket has been inactive for quite a while so I'm transforming this chat into a support ticket because I believe you're still encountering the problem. You'll still be troubleshooting the problem with me and this way we will not lose any progress made so far.
Could you please share your Debug information with me?
You can read the detailed explanation about it here. http://wpml.org/faq/provide-debug-information-faster-support
The debug info will give me a lot of information about how your site is configured and will help me understand the source of the problem.
