So I have a wordpress multisite site for a client who moved to to Sweden from the US recently and has since contracted my for 4 more websites to go to urls with the Swedish TLD (.se). I’m able to login to the sites’ WP dashboards when their urls are set as subdomains of the main site, and I can link them to their actual Swedish urls and have them show up without any issues. My problem is, when they are linked to the domains that they are going to be using, it says I need to enable cookies, which are already enabled, when trying to log in to the WP dashboards for them.

Considering the fact that I don’t have any problems logging in when the urls of the sites are set as subdomains of the main site, i think the issue is stemming from the fact that the domains they are ultimately going to be attached to have the .se TLD. Is there a way to work around this so I don’t have to take the site down every time I want to make an edit?
