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! https://i.nostr.build/5G2XB.jpg  

 I changed mikemonty81 to mikemonty1 and then tried to change mikemonty29 to mikemonty81 and saw the error in the screenshot. So I guess I can’t just change the domain to get the correct theme to display and the domain would be lost to me if I tried to with the current iteration 😅 https://i.nostr.build/Rmja0.jpg  

 Domain isn't released immediately and stays reserved under previous site for a while. Which domain do you need? I will delete it and release and you would create a new site 

 mikemonty.npub.pro please 😊🙏 

 Try now please 

 Got the domain set, thank you for all your help! 🙏😊
