Missing state [error code: unknown] Wordpress Plugin

Hi there,

Currently trying to get the WP Auth0 plugin hooked into our hosted site. Authentication with Auth0 appears to work, but the user is not signed into WP at the completion of the signin process and I receive the error “There was a problem with your log in: Missing state [error code: unknown]”

Is this likely the same issue as the “invalid state” case that is discussed here? Or might something else be the culprit? I’m in contact with our hosting provider to try and exclude some urls from the cache, but I wanted to see if this was the right approach or if the “missing state” was somehow altogether different.

Here are the network calls I see in my devtools (No errors in the WP logs or in Auth0 logs).

Thanks in advance!
Steve

This is an old issue but I got the same… Check for the “Grant Types” in Auth0 application configuration, it should include “Password”.
