Hello, I have a strange problem and I don't fully understand how to deal with it. I wanted to connect my own domain to the site and in the Wordpress settings I pasted a link with a typo, which meant that I couldn't get to the site. Changing the parameters in WP_options in phpmyadmin helped. The problem is that now I can't change the address of my site and I'm stuck with the hosting address. Changing the parameters of WP options or php_config to any other blocks the site from working. I kindly ask for advice on what I can do

mm2001 If you have followed https://www.wpbeginner.com/wp-tutorials/how-to-change-your-wordpress-site-urls-step-by-step, it means that there is still an old, hardcoded address somewhere. Check the database content as well as the website files using grep.
