1 - Hello, how are you? At first, in the login form, in the advanced login link, the login with extension did not appear. Then it appeared. I was able to log in with the extension, but then I could not do it anymore. The system says that I must log in. When I try to log in again, my previous connection, made with the extension, appears in the history. When I select it, nothing happens.

Note: I managed to create websites in this process, but they never appear in the search when I enter the admin because it says that I am not connected or it is not clear if I am.

2 - In the process I created 2 sites as I said, but I only wanted to create one. How could I delete one of them?

Note: I turn off my Shields  from Brave.
 

 Hi! Thanks for the input!
1. Which extension, browser, OS are you on, please? I see both of your sites in admin panel https://npub.pro/admin when logged in as you. I also see them at the site list at /sites
2. In /admin there is a Delete site button. 

 AKA Profiles 

 I cleared the local storage and login up again and works.  

 Awesome! 

 Another piece of information is that, analyzing the browser inspector, I realized that I got CORS errors..

I will report the specific error later. I don't remember now. 

 There might be cors errors due to site previews trying to render various third-party resources (images, link previews etc), that's probably irrelevant.
