Sorry, everything is OK. I just didn’t know that you have to press OK (or something simillar) in order to visit the selected mobile menu item in iOS. In android its just “click and go”…

But I have one more issue to solve. When I update to WPML Multilingual CMS 3.3.5 plugin (or to WPML String Translation 2.3.5), the “white screen of death” shows up and the only solution is the restoration of my site. According to this: maybe there are some incompatibilities between your theme and the WPML plugin.

Are you planning any updates in the future (current version of therestaurant theme:5.5, last update: 10-20-2014)?

Thanks for your ASAP resopone.
