Ive installed this plugin only to have no config file generated on installation.
I have not seen this with any other plugin I have installed.
Any ideas?

Not sure what are you talking about. New config file generated on each plugin load if there is none exist.

I have installed this plugin as I would every other plugin I use on my server. This is the only one I have not had a Config (json) file generated for. Not sure whats going on, on my end as I have installed deleted and reinstalled a couple of times to see if it will generate the file.

Just tested to be sure that it's working as expected and it is.

So the problem must be in your environment somewhere.
