Moved the WP-Content to new location and got problem with themes

I wanted to move the ‘wp-content’ directory to a new folder following the guide at Moving Wp-content. I could able to access plugins directory with out any problem as I used the wp_content_dir in addition with WP_CONTENT_DIR’ .

These are the constraints I used

define( 'WP_CONTENT_DIR', $_SERVER['DOCUMENT_ROOT'] . '/blog/wp-content' );
define( 'WP_CONTENT_URL', 'https://example/blog/wp-content');

define( 'WP_PLUGIN_DIR', $_SERVER['DOCUMENT_ROOT'] . '/blog/wp-content/plugins' );
define( 'WP_PLUGIN_URL', 'https://example/blog/wp-content/plugins');

Now I got a problem with themes. I could not able to access themes and unable to install new ones using theme repository.

Could any one help me to solve the theme access issue?
