I am trying upload an image in media library, on browsing the images its shows that the image is uploading, but after that image could not be uploaded and it shows this error--
top-long-bg.jpg Missing a temporary folder.
wp_config.php and add code
define('WP_TEMP_DIR', dirname(__FILE__) . '/wp-content/temp/');
via ftp in the folder
/wp-content, create a new catalog
