I am trying to connect hyperkitty to mailman. I have cloned and set up mailman-hyperkitty and made changes in the mailman_hyperkitty.cfg and mailman.cfg files. But, still I am unable to see anything in hyperkitty(except the login page).I have injected mails to a list using mailman inject -f email.txt email@example.com but couldn't see anything there except the login page. "No archived lists yet" is shown there. I checked the MailingList model in hyperkitty through command line and found that it is empty.
