Tick this box to execute the checkout script on checkout in the legacy order form in

which is in

"configuration --> general settings"

 

I didnt manage to find out what is it for.

[WHMCS Andrew]

it runs the checkout.php script which is from a very old version and does not come with new versions of WHMCS as it now has actionhooks

[nikos]

so it is not suggested?

and in which cases does it help to run this checkout script?

[WHMCS Andrew]
