error 404 – I can no longer access my WordPress administration page

following an error on my part I can no longer access my WP administration page: I changed the main URL name by naming it like that of my home page in the "settings" tab from WP. And boom. enter image description here My host (Hostinger) found what he calls a "code problem" but cannot fix it. I did their FTP procedure but nothing works. It's been several weeks of work on this site, I'm a little disgusted. Can anyone help me? Thanks in advance (sorry for the translation i'm french) I reset the site to FTP with the latest version of WP without success. I clear DNS cache and browser cache, without success. I hope recover my admin page.

If you have access to your Wordpress installation's database, perhaps through phpMyAdmin, look inside wp_options table for the row with the value 'siteurl' under the option_name column. Inside this row, you will find your main url under the option_value column. You should be able to access your admin area via this url by appending the subpath '/wp-admin' to it (if the value is http://example.com, the path will be http://example.com/wp-admin). If, despite following these steps, you still cannot access your admin area, ONLY AFTER MAKING A BACKUP, update this row with the original main url in place of the url currently saved. Good luck.
