It looks like that your problem got solved. As George said that is usually a permalink/.htaccess issues which you can simple reset by navigating to

“Settings -> Permalinks”

and then click the “Save” button below.

Are you using any custom plugin for user registration on your website or it’s your theme’s built-in functionality?

Did you check it after disabling gravity form plugin? Is that [L] still appears after your title?

Hello abdukannur,
You are getting this error because WordPress is unable to create a connection with your database. Kindly update your wp-config.php file with new details,

/** The name of the database for WordPress */
define(‘DB_NAME’, ‘database_name_here’);

/** MySQL database username */
define(‘DB_USER’, ‘username_here’);

/** MySQL database password */
define(‘DB_PASSWORD’, ‘password_here’);

/** MySQL hostname */
define(‘DB_HOST’, ‘localhost’);

1and1 doesn’t support localhost as MYSQL hostname so you have to update it as well to establish a database connection.

I thought that problem is with wp’s file because admin-ajax.php is a wordpress core file which is returning an error.
