I am running Moodle 3.10.1 (Build: 20210118).
I've set up a site using the Moodle Cloud trial to play around with something and I cannot enable web services as an authentication method for users.
I have enabled the web service authentication plugin, I've made sure web services are enabled under Advanced Features but when I go to create a new user I can only see Manual accounts.
I'm also having trouble setting up a web service and get "invalid_parameter_exception" when I try and post anything. Hopefully its related and if I can set up the web services user correctly it will work, although I have tried to also set a token for the admin account and that's got the same error.
Please let me know if anything else is needed.
