Why do plugins/themes fail to update?

If you cannot update your plugins/themes or you receive FAILED update, the first thing you should try is to update them from your WordPress interface, to validate that it is an issue with WP Time Capsule specifically, and not the site itself.

The most common cause of this problem is that your website requires FTP information.

You can correct upgrade issues by adding FTP information in your site’s wp-config.php file.

Note: Do not add this to the end of the file, but just below the database information on the top of the file.

define('FTP_USER', 'username'); 

define('FTP_PASS', 'password');

define('FTP_HOST', 'ftp.example.org');

More complex update methods like FTPS or SSH are also supported if you enter the appropriate details in the wp-config.php file. For more information on FTP/SSH upgrades, click here.
