403 error when creating an event

You get

Error 403 'You are not authorised to view this resource'

when attempting to create an event when logged in as a super admin then this is probably the explanation:

• You enabled authorised user mode for event editing/creation
• You did not set up the super admin user as an authorised event creator

To fix this setup the super admin as an authorised event creator or disable authorised user mode.

Event creation permissions (and other config options) are described in the configuration documentation available to all club members (bronze, silver and gold) available from here.
