thanks Rouslan ....but you mentioned that origin is my repo and upstream is pma repo But I want to clarify more about it what did you mean by my repo and pma repo ? my repo = repository in my local machine not forked repository pma repo = original repository that under this link (https://github.com/phpmyadmin/phpmyadmin.git) is that you mean?
but I cloned PMA under forked repository (https://github.com/<my user name>/phpmyadmin.git)
so then upstream is that forked repo and origin is local repo....isn't it?
thanks and regards
