Page load error? Cannot run workflow -- Relies on invalid inputs

Hi all,
I am getting this error message (Cannot run workflow – relies on invalid inputs) in the debugger when I load any page.
The debugger is not telling which step of the workflow is generating this error.
Is there a way to inspect deeper?

I am thinking the error might be in my Header page but can’t find the issue.

prolo_header page, which I load in everyone of my pages.
