re: So first, I’m not sure where the file that is the main plugin “Connections” is found?
Connections is here: https://wordpress.org/plugins/connections/
You can install if from the Add New Plugin admin page. Step one on the QuickStart doc page is the easy way to install it.
re: I won’t renew a Pro license again if I have to buy the CSV each time, it doesn’t seem very economical to have all those templates. And once I have used the CSV to upload a group of files, can I disassociate it from a site and use it on another?
Since all templates and extension are GPL licensed I can not dictate where you install and how often. What the support licenses grant you is support and updates (including compatibility/security updates) for a single site. For example, say you installed Gridder on three of your client sites. Only the site that has the support license if is activated on will receive updates. As for economical you have to determine if there is value to your client that they receive updates and build that cost into you support contracts. That’s not really anything I can help you decide. I can tell you, generally, other will purchase a license for each site that they develop for a client pretty much for the reasons I just stated.
Hope that helps!
