I am developing a wordpress theme. For adding the custom background option to my theme I have added the code in the functions.php
add_theme_support( 'custom-background' );
here I didn't put any function for default settings for background. And also my header.php is look like this
<?php wp_head(); ?>
</head>
<body <?php body_class(''); ?>>
as wordpress documentation suggested(Watch here in the wordpress codex).
After completing these steps, from wordpress Dashboard -> Appearance -> Backgorund settings it's only working for color's not working for images. Then I inspected form google chrome and in the css properties of body tag I found this
background-image: url('[site_url]/wp-content/uploads/2013/07/Tulips.jpg')
So I have understood that there is something problem with the image url.
Any one can help? Please.
