wp-admin page won't load

There’s two addresses in the General Settings panel of the WordPress dashboard, WordPress Address and Site Address. If I’m understanding the problem correctly it sounds like you’ve changed one of these address and caused the dashboard not to no longer load correctly.

If that’s the case you can temporarily fix this problem by adding the following constants to your site’s wp-config.php file.

define( 'WP_SITEURL', 'https://kalpanasingh.bulletproofbranding.biz' );
define( 'WP_HOME', 'https://kalpanasingh.bulletproofbranding.biz' );

Note that if your WordPress installation is located in a sub-directory you’ll need to include that in the WP_SITEURL constant as that defines the absolute URL of your site’s WordPress location. This typically is not the case so the above code should work just fine.

You can read more about those constants here: https://codex.www.ads-software.com/Editing_wp-config.php#WordPress_address_.28URL.29

To revert this change permanently you’ll need to gain access to your website’s database administration tool (usually phpMyAdmin). Once you’ve logged in you’ll need to either the home or site_url value in the wp_options table back to its original setting of https://kalpanasingh.bulletproofbranding.biz.

After you’ve completed this step you’ll probably want to remove the edits you made to your wp-config.php file earlier as they’re no longer necessary.
