QA finding
A script or stylesheet with an integrity hash is blocked because crossorigin is missing
QA Error Severity: High
Part of the audit Page resources and script errors. Finding id: qa.integrityWithoutCrossorigin.
What it costs you
The browser refuses the file. Whatever it does on the page (a menu, a form, a payment step, the styling) silently does not work, and nothing in the page tells the visitor why.
What to do
Add crossorigin="anonymous" to the element, and check that the host sends Access-Control-Allow-Origin for the file.
What it checks
- Script blocked by a security check
