I think i discover how to reproduce the problem...
When i receive on my email account the warning email telling my listing will expire in 2 days, when i press republish link in the email the listing is republished, but is marked as inactive because dont ask to login to my account on the site.. just republish...
I think this is as bug, when i press republish link in the email, first shoul ask to login in into my account on the site and then republish, of course, should first accept terms and conditions...
Result is republished listings, but marked as inactive..
