saguaros now i understand. Didn't know that the menu blocks were already "added" when importing to a new page. That makes sense. I used my pre 1.05 pagebuilder to make the changes, but i should have done a complete new page import instead.
When looking at the just imported page the off-canvas menu is not working ? Can you have a look at it ?
Also when you hover over a menu with additionel menu-items it does not expand out of itself... you have to click to menu to expand !!!! Can you also check that ?
