Problem when trying to register in the user

Good morning everyone.
A few days ago we are having the following problem, when trying to register a user be it:
Reader, Author or Evaluator, using the portal (external without being through the administrative area), the following message is displayed: “The typed login is already registered” this for any informed login. The curious thing is that neither the login nor the email entered in the form are registered.

Has anyone ever been in this situation?

Thank you very much in advance.
Regards,

Grateful.

Hi @Est.dpu,

This user is probably already in your database but potentially not associated with any particular journals. If you can’t find them in the Roles area of Journal Management, try Journal Management > Show users with no role. Both usernames and email addresses must be unique to each account.
