Just as those who wrote in that topic. I installed the plugin, I made the correct settings in the administration area, but does not appear as alternative payment. I attached a picture ..
The problem is the min price field is missing in install.xml and pre.gateway.php.
Please contact the support and open a ticket.
I think the Flynax Team has uploaded a wrong version!
The allowed price of your country detect automaticly. If the price of a listing plan more acceptable price in your country; then the payment gateway "smscoin" will be hiden.
So, make me understand, please .. I can fix the price from the "price plan". Okay. So where should I look on smscoin.com, to put a correct value (the "pricing plan")?
