The same thing happened to me too. Furthermore, I cannot edit the choice of notes or posts, nor the choice of tags.

This should have been fixed this morning, please reload the page and try again, thanks!

It happened again, I like the Attila theme and switch to that to test and see if the issue was resolved but it make a third site 😅 I understand we can change our domains, say I change the original to something else, does that free it up to be used for the theme I tried to change it to? Or should I wait for the ability to change themes on an existing site to be fixed? Ty!
