When i want to update the wordpress theme or plugin, i will get the following error “PCLZIP_ERR_MISSING_FILE (-4)”.
Solution :
1. To fix the following issue, please add define(‘WP_TEMP_DIR’, ABSPATH . ‘wp-content/temp’); right after }! and create temp folder in wp-content/temp.
if ( ! defined( 'ABSPATH' ) ) {
define( 'ABSPATH', __DIR__ . '/' );
}
define('WP_TEMP_DIR', ABSPATH . 'wp-content/temp');
2. Create tmp directory under wp-content in documentroot
# mkdir -p /var/www/html/wp-content/tmp
