Hi
we have an multi language website and in the template style of the dutch version i changed the column settings of the header layout. I changed the class of the column for tablets. This did ot have the effect i wanted so i changed it back.
After doing this the menu is gone over the complete dutch website, only it is visable on the homepage.
Also the module section menu is gone, i can't select it in the column settings.
The german website works fine, also there you can see the menu section in the header layout of that template style
Hope someone can help us getting the menu back.
