when I was using localhost:81 the wordpress admin worked but the website itself show an empty screen

when I change the siteurl to 127.0.0.1:81 both admin and website are not working and show the following error

Answer 1

Did you assign Port 81 to IIS. Default PORT for unencrypted networks is 80. For admin Panel, try localhost/wp-admin or 127.0.0.1/wp-admin or Try Router IP address assigned.

Both PHP errors and database errors can manifest as a white screen, a blank screen with no information, commonly known in the WordPress community as the WordPress White Screen of Death (WSOD).

If your database cannot be connected, search for wp-config.php and change Database Username and Pass. Also, If you still cannot install, start an FTP connection with Home directory of Wordpress and try Softaculous FTP installer,
