Resend Verification error

Greetings.

I’m experiencing the following issue.

Once i register if i leave the login process until the first verification email sending, i need to go back to login to finish the process, what do i mean, i log in with my credentials but when appears the notice that the verification link needs to be to complete registration appears the following error (twice)

Undefined index: login_remember in /home/racertrader/public_html/tests/wp-content/plugins/ppress/classes/class.login-form-auth.php on line 39

I’d like to know how can i solve this.

Thanks in advance
