Change of domain names then it stops working

I started a page on 1and1 using https://www.paintersofbali.com but all along intended to use https://www.artofbali.com after i moved it to 1and1 from go daddy. I got it moved and in the 1and1 control panel switched https://www.artofbali.com to /wordpress and the forwarded https://www.paintersofbali.com to https://www.artofbali.com. After that it just went to a wordpress page where I couldn’t log on.

I switched the domains back to the original settings and everything went back to normal. Then I went into the options panel and switched the addresses in the two middle boxes to https://www.artofbali.com and saved that. Then i switched the domains back again, making wwww.artofbali.com go to /wordpress. After that the page came up with no. These results were worse. now going to https://www.artofbali.com still just gets me to the “my webblog” screen where I cant log in and when i aim https://www.paintersofbali.com back at /wordpress I get the page but the links in the banner aim to https://www.artofbali.com, which means aims nowhere. To top it all off when I use wp-admin to try to login to edit I get no response.

I need to find a way to get back into the admin section
