[MM3-users] Footer broken after migration. Where can I fix it?

Dear all,

after importing the lists from mailman2, almost everything works great, but the footer templates appear broken. Mails sent out contain the line

%(web_page_url)slistinfo/%(_internal_name)s

So clearly the old templates are not getting explanded.

However, when I look in the web interface unter "templates", there is nothing there.

Where are these legacy footers stored? In the DB, the table "postorius_emailtemplate" is empty.

Thanks!

Johannes
