I did the test:
When I go to “Sales by date” or “/reports/sales_by_year”

That I only fill in the date fields, it works.

If I fill in the quantity fields, I get an error message in a red screen:
An Error Was Encountered
The action you have requested is not allowed.

But I did the test by refreshing the page and there I was able to have the report.

Between each attempt to create a report, the page must be refreshed.
