I can't login with SSO after Discourse Upgrade

Hello, I’ve been using WordPress as my sso provider for a while now and it has been really helpful. The problem I am facing is that after I upgraded discourse(last week), my users can’t seem to log in. When they try to log in they get this:

Previously logged in users can access the site with no problem but once you log out and try to log in you’ll get the error above.
I was also locked out but was able to login through mysite/u/admin-login. I believe this is for admins only so now most of my users are locked out.

That’s really strange!

What does [your.discourse.url]/logs say? any errors that relate to login issues?


Thanks for your reply. Under my logs I can see this error

TypeError: Cannot read property ‘extend’ of undefine

Can you provide us with the backtrace?

This is what is in the backtrace.

Hmm that is only part of the backtrace. Is that all you see when you click on the backtrace tab



Yes that’s all I can see in the bactrace tab.

Hmm anything in info?

This is what is in the info tab.

What happens when you open the site in /safe-mode?

Thanks for your responses but I still get the login Error even in safe mode so I guess its not the plugins.
