I set up POL on my Ubuntu And tried to create feed for my test page: https://music.slavikf.com/logs/test2.php

And I got HTTP 500 for /setup_create_feed page

Request body:

Same page works fine on public site

ok, fixed by this:

ALTER TABLE frontend_feed ALTER `owner_id` SET DEFAULT NULL;
ALTER TABLE frontend_feed ALTER `name` SET DEFAULT NULL;

Can you add that, as a migration?
