Exception: Excepción al control de acceso | DEBUG INFO: Access to the function core_course_create_categories() is not allowed.
There could be multiple reasons for this:
1. The service linked to the user token does not contain the function.
2. The service is user-restricted and the user is not listed.
3. The service is IP-restricted and the user IP is not listed.
4. The service is time-restricted and the time has expired.
5. The token is time-restricted and the time has expired.
6. The service requires a specific capability which the user does not have.
7. The function is called with username/password (no user token is sent)
and none of the services has the function to allow the user.
These settings can be found in Administration > Site administration
> Plugins > Web services > External services and Manage tokens. | ERRORCODE: accessexception in /home4/g/public_html/moodle/webservice/xmlrpc/lib.php:94
