Unable to log in to the dashboard to get the affiliate links..Urgent

I am using this (https://wordpress.org/plugins/affiliates-manager/developers/) plugin. I have two links in the affiliate page: login and register.

The register link works and let the affiliates fill the form for registration but the affiliates are unable to get the affiliate link after that.

They are unable to login to the dashboard because it is asking for password and they were not given an option in the beginning to set the password so how will they set it.

people are redirected to a page where it shows:

AFFILIATE LOGIN
You are currently logged in

Username: XXXX
Email: [email protected]
Log out

But it’s not redirecting to dashboard and check the statistics and get the affiliate link.

Can anyone help me with this?

Thank you a lot!
