Most Web Hosting companies configure WordPress so that it automatically updates whenever you click on upgrade WordPress or WordPress plugins.  Some web hosting companies have this feature turned off.  If you have an VPS Hosting or Dedicated Server, ask them to install suPHP, if not you can add the following codes to your config.php file so WordPress automatically remember your FTP login and password.

 

For VPS Hosting, we recommend WiredTree, ServInt and Future Hosting
For Shared Hosting, we  recommend HostGator
