I received a dm stating that phab.miraheze.wiki is erroring with the following:
This Phabricator install is configured as "https://phabricator.miraheze.org/", but you are using the domain name "phab.miraheze.wiki" to access a page which is trying to set a cookie. Access Phabricator on the configured primary domain or a configured alternate domain. Phabricator will not set cookies on other domains for security reasons.
