Cannot load unsigned plugin

Hi
I’m trying to install this plugin GitHub - spectraphilic/grafana-windrose: Grafana Widnrose panel plugin
I cannot get it to load.
I have set the mode to “development”.
I have added it to the allowed list of unsigned plugins.
I have (re)set the file permissions.
I have hard refreshed the browser, tried incognito mode, tried a different browser

I still get the error “Skipping loading plugin due to problem with signature”

Any other ideas or help would be greatly appreciated…

I’ve found a discrepancy, in the grafana.ini file I have
;app_tls_skip_verify_insecure = true
but in settings it is showing as
app_tls_skip_verify_insecure false

I have fixed it, the problem was that I did not realise that “;” is a comment!
