Admin menu path to: Enable Form Key Validation On Checkout

Question

After installing patch SUPEE-9767 the "Enable Form Key Validation On Checkout" warning appeared and from the link provided in that warning I was able to enable Form Key Validation.

But, after having some issues in the checkout process I would like to try to disable it and check if everything comes back to normal.

The big problem here is that I cannot find where the option is in the admin menu.

I seem to recall it was in:

System > Configuration > Advanced > Security > Enable Form Key Validation On Checkout

But if it was there, now it has disappeared. Do I recall it wrong or what might be the issue?

Answer 1

Close! It's under System > Configuration > Admin > Security > Enable Form Key Validation On Checkout

Answer 2

How I fix it on Magento 1.9.3.7. with php70

1. disable Form Key-just ignore the security message (if your theme does not support formkey -ask from whoever you bought it if theme supports formkey validation)
   To disable go to Configuration>GENERAL>WEB>Security>set to NO

2. Fix your Session Cache Settings in Configuration>GENERAL>WEB>Session Cookie Management to:
   Cookie lifetime=3600 -default
   cookie path -leave empty
   cookie domain -leave empty
   use HTTP Only -set to YES (it's ok-because in url secure and unsecure i have https for both + ssl
   Cookie Restriction Mode -Set NO

3. Clear Cache

4. Clear Session logs (go to your public_html/var/session folder in hosting and delete everything ((your cron jobs should be set also for this folder -check with hosting

5. clear browser cache
   login or do the checkout-is it working?
   If not -disable temporary any captcha plugin and test again
