Administration menu does not appear anymore

I’ve refactored my application but now the admin menu is gone…
I didn´t played arround with the permissions or something. As far as I can see in db the admin user has still one role.
But I do not see any error in the logs - I have no idea where to start to search for my mistake.

kind regards

Hi Christian,

That could happen if you switched the app menu from composite to single mode. Check this in Studio or in file:

+cuba.menuConfig = com/company/demo/web-menu.xml - composite
cuba.menuConfig = com/company/demo/web-menu.xml - single
