I asked someone from fiverr app to do the job.. And you can consider it resolved. Thanks
Even for the free version (there is no place to enter customers credit card numbers!
I mean when a customer wants to buy and checkout to payment there should be a place to enter credit card number (this place is not there!)
I uinstalled this plugin and installed it from different author (github) and it worked well!
But if i want to return to your plugin, how i can solve this issue? I beleive that even the free version should have place to enter credit card numbers!
