We will learn how to change its dimensions.

   			.single .post-thumbnail__img {
   			width: auto !important;
   			}
   		

   and click on “Update File“.

   

2. Connect to your FTP or use hosting Cpanel File Manager. Follow this path: wp-content/themes/themename/config to locate thumbnails.php file.
