Note that your password for the WP.org forums has NOTHING to do with your website passwords.
I’m not sure what I’m looking for. The only thing I know is that all of a sudden both link to my website as well as the link to the WP-admin dashboard are dead, and I can’t reset my password on ww.wp.xz.cn since it’s linked to an old email adress. I literally don’t have a clue what to do, and on top of everything I am the least technical person alive. It would be preferable if WordPress offered a livechat or a phonenumber to call, but since that’s only available throught the premium account I now can’t access, I am literally clueless.
Thanks for your help though, even though I couldn’t do much with it
Please read that link carefully. Using the PHPMYADMIN method, you can reset your password *and* change your email directly in the database.
There is no “premium” account — ww.wp.xz.cn distributes software. If you contact your host, they may reset your password for you. It can’t hurt to ask.
