Has anyone seen this error when using the Stripe button? In the button you configure a success page and a failure page. For me these are just static .html pages. After a payment Stripe redirects to the page but the Apache server gives a 406 error.
It is coming from mod_security which I have disabled by adding the following to .htaccess but it is still happening.
