The job is simple, do the following. 1. Build in Payment Gateway in opencart 2.1.0.2, the specific gateway is from wannafind denmark, documentation and download of the php example is here: Documentation: [login to view URL] Download api, example php and so on: [login to view URL] 2. There is a small bug in category rating, at the moment it shows up buggy, there must be rating on all products also when no reviews, this is buggy at the moment. 3. All add to cart buttons must be replaced with png buttons, these i provide of course. 4. Add we use cookies notice. Please note this is a sexshop, so if you have a problem with that DONT bid. This is not a big project and time is really important, should more or less be finished yesterday, so if you have no experience on the matter or not time to start right away DONT bid. Bidders that does not comment on the points in the description, will be ignored. Thank you in advance
