made new directory for wordpress but can't log in

Hi,

I have changed my wordpress files so that they in the root directory (as opposed to on my iweb site).

My url used to be anniehearts.com/blog
and now it’s anniehearts.com

I changed my index.php file to:
require(‘./blog/wp-blog-header.php’);

My problem is that now I can’t login.
Codex says to:
Login to the new location. It might now be https://example.com/wordpress/wp-admin/

I tried this but it didn’t work.

Any help is appreciated!
