I searched over Google for the answer, but could not get any concrete answers - I have uploaded Payu money (Payment Method - zipped file downloaded from payumoney) in app folder (hosted at Godaddy) and Extract it and executed the following commands on the server (using ssh)
php bin/magento setup:upgrade
it is showing some lines and then "Nothing to Import"
php bin/magento setup:static-content:deploy
then i used
php bin/magento setup:static-content:deploy -f
then some lines executed up to 100%
then i checked store -> configuration -> sales -> payment method, but PayU is not showing there in admin
then I searched google and found it may be some problem in system.xml for , then when I searched for system.xml in my public_html folder (on Godaddy server) I found multiple files, which I am not sure which is to edit?
