Just got this in a report from the magento security scan, do you know how to fix it
I think this is known issue !
Some one has already report this kind of issue and got solution from here , Refer this link - https://magento.stackexchange.com/questions/176871/security-patch-supee-9767-possible-issues
You can also refer this link - https://community.magento.com/t5/Magento-1-x-Security-Patches/SUPEE-9767-Customer-Registration-Fails...
i dont see anything there relating to my security warning "Failed. NON HTTP 200 response expected for '/index.phpcheckout' (APPSEC-1622)"
