i lost my website how do i get it back?

Hi what did you change the name to? if you did change it try and access by going putting the new name after the https://localhost:8888/

Go into your wp-config.php file and add these lines like:

define('WP_HOME','https://localhost:8888/twdbreakingnews');
define('WP_SITEURL','https://localhost:8888/twdbreakingnews');

This will get you going again.

I encourage people to use the “Virtual Host” technique rather than “localhost”, details here:

And hosts file:
