No instructions on how to have it show up on your sign up page...

I installed it, set up the the facebook login authorization and made sure it was enabled. But when I log out and try to create an account it doesn't show up and there's no block to show how to login with it either.

Running into the same issue. Did you find something about this somewhere?

What version of Moodle are you running? I had the Google button working, but when I updated to 3.1.1 the button disappeared.

I managed to get the button back by pasting the code provided in the settings page into the index_form.html file just below the usual sign in button. Plus, checking the box to have the button displayed at the top of the page.

I would like to have it in a block on the front page.

I notice this problem too, I'll have a look. It is was on 3.1 only - I suppose some caching cause the issue...

Did you solved this issue ? If loginhttps option is enabled, the button does not show in login page: it's a known bug.
could you tell me what moodle/oauth2plugin version are you using ?
