we have tested our CF theme locally ,and everything is working fine and we can add specific sidebars easily. you have now another problem we found while we was testing your website is that when we add a page and tried to view it , the website went to the homepage instead of going to this specfic page. so it seems maybe you have customized something in WPML Plugins or even another customization we don’t about it. So please give us more information about what you have customized exactly.
PLease don’t hesitate to contact me if you have any further questions,
