Font-Awesome cannot save settings

[OrbisEricCoumans]

When I try to save the settings the Font-Awesome plugin returns an error "Update failed". The console log returns; Failed to load resource: the server responded with a status of 405 () /wp-json/font-awesome/v1/config:1 My local (php/mysql) environment works fine. Our online Project Nami returns this error. Any idea why this is happening?

Anything in your PHP error logs which might indicate a failed database query?
