XSL_Transformation on 12.1

Hi,

I get this error on my XSL_Transformation block in my Transaction:

[ERROR] [XSL_Transformation_1]XSLTransform error: Could not compile stylesheet

This happens in the new Box we just configured not in our old Box. Old Box works like a dream.

Both box on 12.1.8 Build(36)

Any one has an idea whats going on here?

Regards,

Bheki
