I develop a new enrolment plugin . but in couse administration \ course \ Enrolment methods . I haven't see the new enrolment method.
Why?
You might have forgotten to activate it for the whole site:
Site administration > Plugins>Enrolments> Manage Enrol plugins
BTW: Did you develop a new enrolment plugin (how does it work) or installed an existing, esternal one?
Thanks.It's worked.reinstall this plugin.
