If you’re a new WordPress users, or perhaps even a veteran, you may have noticed an inability to work with your widgets at Appearance -> Widgets in your Dashboard. This is fortunately not common, but it can lead to a ton of confusion and many hours of frustrating attempts to fix it. First, make sure that your browser has JavaScript enabled. This is usually the most common cause of the issue, and fortunately the easiest to fix. If your browser does have JavaScript enabled, use an FTP or SFTP client to access your server and a plain text editor to edit your wp-config.php file. Once the file is open, adddefine('CONCATENATE_SCRIPTS', false); below the define('DB_HOST' line and save the file. In most cases, one of the two methods will work for you. If you’re still having trouble, stop by the WordPress Support Forums for further assistance.
