Hello, I have a local installation of Knowage 7.2.6 on Windows (64 bits) in my personal computer. I want to start modeling something so I try to uploading a file, first I try with an .xlsx file then I try with a CSV file; but for both I got this error on the page FAILURE THE FORM CANNOT BE SUBMITTED BECAUSE OF SOME FAILURE.
I thing that is a web browser issue so I try with google chrome, Microsoft Edge and Firefox; but the error shows in each of them
What is wrong on the setup?, it is related to an specific issue, or casual?
