I've got a subdomain "givemobility.stanpr.org" in which I installed Wordpress 2 days ago but I am not able to log in. I get "404 Error - Page Not Found" on the top, then "Site Under Construction" below it.
I had set up another subdomain in the same root folder before and everything went smoothly, don't know why this one is giving me so much trouble.
First review the dns and make sure the domain name points to the right IP address of your hosting account.
If you can verify that is correct then the next thing to do would be to identify... Why when visiting the website givemobility.stanpr.org does it go to the address 18.104.22.168 in the address bar instead of remaining givemobility.stanpr.org
either you have an issue with the database site url or a mistake somewhere in your dns.
