how to put the (PAYMENT_PRO_CRYPT_KEY) in config.php

[joecoolll]

hi there.

i'v done all the searches here and could only find 1 thread about my problem, all the other threads are about index.php, but mine says in the config.php which there isn't one, so i guess i make one and add the key.

how do i add the key please ? and is less than 50 characters please ?


thank you. 


edit: i found this https://forums.osclass.org/plugin-payments/payment-pro-config-php/  but it doesn't say how.
