How to Hide Warnings on WordPress

1. Log into your WordPress installation. The login page is usually located at http://www.yourdomain.com/wp-admin/ (replace yourdomain.com with your own domain name). This will differ if you've changed the URL structure for your WordPress blog.
2. Click the 'Screen Options' button, which is located in the top right-hand corner under your name.

3. Uncheck the boxes next to any of the warnings you'd rather not receive on your dashboard page. For instance, you could uncheck the box next to 'Recent Comments' to remove that box from your dashboard page.
4. Click the 'Screen Options' button once more to hide the menu. Any boxes you unchecked will no longer show on the WordPress dashboard page.
