I get this error into error log on forgot password
Can you please indicate the specific version of OJS that you’re using (e.g. 3.3.0-7)? This will help in troubleshooting your issue
If you are still facing the issues; you can try login as Journal Manager or another user who has editor access and follow the below steps;
Go to Users & Roles > Users
Select the User who can’t log in and click on the blue arrow next to their name
Then Click Edit User below
And now enter a new password;
Select the box next to User must change the password on next login
And now, you can try logging in using your account with a new password.
If you still face the issue, you can use this “Troubleshoot: Unable to login” section on this OJS Guide. You might get a solution!
Hope this helps!
