VB4 Style on a 3.8 Board
 

I try to put a VB4 Style in a 3.87 Board, but it doesn´t work. Ist there a chance to ingegratet this?

Not unless you know exactly what to do, there is a lot to change.

maybe anybody knows it. I have only the xml of it. Whenn I install that, it came webserver not available

In short, you cannot do this, they are incompatible.

With a lot of work on the templates and changing your css you can, however why re-invent the wheel, just download the vb4 version you can and have it done properly!
