I run a Discourse instance and WordPress site, using the Discourse SSO plugin (which is awesome).
Recently, two (out of 50+) had
1 appended to their usernames in Discourse. Their usernames on the WordPress site remains unchanged.
I tried to manually edit their usernames back in Discourse, but encountered the error message
Username must be unique. However, the username (without the
1 appended) is unique.
Is this a known issue? Is there a workaround for this problem?
Happy to provide whatever other info would be useful for debugging.
