I couldn't write an article for a long time because I was busy creating a WordPress site. I added a login and registration option to my WordPress site. But when I logged in as a guest, I saw that the toolbar in WordPress is also showing here.
I did a Google search to fix this problem but couldn't find anything. Then an idea came to my mind that its PHP can be removed.

So fast go to your WordPress Dashboard > Appearance > Theme Editor

Now click on  Theme Functions

Theme Functions also called functions.php

Theme Function Location

 Now add this the below PHP code on the under of Theme Functions

add_filter('show_admin_bar', '__return_false');

Add This PHP Code Like This

After adding this code just click on Update File. Now all done. I hope you are enjoy this article .
