Hello i just installed Coupons 2.2.0 and can not find configuration in menu...
What is more strange that i have clean install of 4.7.0 and see coupons there without any purchase :(
But what i made before is migrated joomla and shop from 2.5 to 3.0 The way i made it is:
1. Made fresh install of J3.3.0 + shop 4.7.0
2. Installed MultyCurrency plugin
3. Updated database schema for 2.5 database jos. tables from 4.7.0 version
4. Renamed one product table field as written in manual
5. Moved all table data 2.5>3.3 for .jos tables
6. Shop was fully functional with all config and users, items, orders and so on...
I was not able to get shop running by using your manual where it is said to move all tables to new installation, configuration table was different in size, i tried to copy only data but shop was inactive. SO only way i figured to get working shop is as i described.
Now i was able to download Coupons 2.2.0 after processed payment and installed it and see no such field in options. Plugins installed fine.
