Bonjour Justin, merci pour ta réponse.
Good question. I have limited knowledge in programming and don't really know the answer. I upgraded from 4.3.0 to 4.8.4 and enabled the Tracker plugin for the first time. I have a Contemporary Install. Here are some of the details:
I have a .dada_config file and a dada/DADA/Config.pm file. I don't really know the difference between the two. I have been configuring the dada/DADA/Config.pm file.
The package uses a MySQL database.
I thought the tracking of Clickthroughs by Country would come automatically with the pluging. I may have to live without it if it gets too complicated to enable.
