menu not showing up when logged in as member

Hello

Then i am logged in as a member the Menus are disappearing on the Homepage, Archives and Category listings and as soon i go to a single post or page they showing up.

Second problem is that the main language of the Website is Portuguese and changing from PT to EN or GE as a member the content is not showing up only the categories names and the ads but no text and pictures of our content.

If i am logged in as an admin or not logged in at all the Website is working without any problems.

Here the link http://eco123.info Theme is Sahifa and translation done with WPML.

Many thanks
Dieter
