jsconnect gives users errors, and configuration panel is not accessible after upgrade
I am trying to upgrade a client on Open Source Vanilla. I am going from 2.2.1 to 2.3.
After upgrade, I changed to Bootstrap Theme.
The client has SSO enabled. SSO users are no longer able to sign in after the upgrade. Users get the following errors after they sign in:
'Provider is required'
'UniqueID is requried'
'The connection data has not been verified'
Some users, including myself, get these errors, but are signed in anyways, despite being displayed these errors.
In addition, I am not able to edit the current jsconnect configuration, or create a new one. It seems like the whole admin section is bugged somehow.
Does anyone have thoughts on what the cause of this could be, or next steps for troubleshooting?
Thanks in advance!
