I have an open cart over a month and a half, only the problems, a bit discouraged
I bought theme 2.2 and you can upgrade to 2.3 because I have ADMIN, in my language, I bought version 2.3
Anyone who wants to help and expert features in the DB I will give him permission to Login
To server

There is lot of difference between 2.2 and 2.3 version.
The time spent in fixing shall be less then buying a new theme
