...and now I am trying to change in TopBar and Header and Footer etc. the colours and it refreshes (short blink), reset button appears, but no color is adjusted... Not even the predefined colors.... Not even after a restart of everything... Loosing nerves here, really.
Update: When I use the preset colours, only the logo and login color change, but nothing else, even if I have changed the color in the preset. Not talking about the custom colours, they don't work at all...
