I've added a toggle feature (in internal settings) so that user api creation can be disabled while form registration still can be enabled.
Also, the /api/user endpoint shouldn't require authentication. Even if we check the authentication when sending a GET request, to retrieve current user information.
I've moved all the internal settings definition to config to avoid duplicated place to define them.
I don't know why we didn't did that earlier.
In case user wants a fresh version of the current one and the website isn’t available, don’t erase it with a boring message saying wallabag wasn’t able to refresh the content.
