We are integrating Auth0 with the Wordpress plugin. The set up has been working for weeks now – first in development, and then launch last week. Two days ago a couple of users received this error when trying to log in:
“There was a problem with your log in: There is a user with the same email. [error code: unknown]”
This error appears to be coming from the Wordpress site – the message looks like a standard Wordpress error message, and the user history in Auth0 shows a successful log in. No errors are reported in the log on the Wordpress site.
The only way I’ve been able to resolve the issue for these clients has been by deleting and recreating their accounts (both Wordpress and Auth0).
But now many more users are running into this problem (both brand new users, and ones who have been using the tool for a few days) AND the fix of deleting and recreating their accounts is no longer working. Of course, I have not been able to recreate the error with my own test accounts, only with accounts for users who have reported the problem.
The only thing that has changed is that on Friday we moved up to a paid-level account with Auth0. But everything was working fine for a couple of days after that, and some users are still able to log in without a problem.
I’ve double-checked the set up instructions “Configuration of the Login by Auth0 WordPress Plugin” in the Auth0 docs.
Wordpress vs 5.3.2
Auth0 plugin is up to date.
I’d appreciate any suggestions.
