Getting error "Error applying XSL stylesheet to XML" when creating KM/Coll content

Hello Experts,

I'd like to ask for your help.

We're running Netweaver 7.30, when I try to create "News" content (click on link to open News form), I'm getting new error window named "XMLFormsServletResponse" with follow error:

XML - Forms

Error applying XSL stylesheet to XML

Default trace output:
