I tried checking current configuration via api but I receive an error response:
403 forbidden
You don't have the permission to access the requested resource. It is either read-protected or not readable by the server.
I can query other resources such as media, or importers, but there are a number of resources that give errors: tasks, objects, relations, living, timelines all give:
404 Not Found
The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.
Only config gives a 403 error.
All other resources (people,families,places,events etc.) are working fine.
