Thanks for contacting WPML forums support. I'll be glad to help you today.
1) First of all, sorry for the late reply due to a higher workload. I need your permission to take a local copy of your site using the Duplicator plugin to debug the issue.
2) Could you please share your Debug information with me?
You can read a detailed explanation about it here. (http://wpml.org/faq/provide-debug-information-faster-support)
The debug info will give me much information about how your site is configured.
