I am working on a Wordpress installation, that another developer used to do. I have an issue since he was working only with Child Theme Directory whereas I didn't.
What I want to do, is to edit the source code of a plugin. I read the documentation but I am not sure if there is something there about it.
Will I just copy paste the file in the child directory and edit it or I must mention somewhere that I have edited this file and it should load it from the child directory?
The child directory has already created with many files, previously from the other dev.
