Localhost missing

Hello,

I just changed my site url from localhost to my domain name. I didn’t know that the migration process probably takes more than just changing the url. So now I can’t access my dashboard, when I click into my localhost file it goes to blank. I also went into the wp_options and changed it back to its original url but it’s still blank. So I can’t make changes or view my site anymore. Is there anyway around it to make it appear again?

Thanks,
Bernice
