Upgrade WordPress without FTP

Open /wp-config.php

Now the first thing you need to do is to open the wp-config.php file from your WordPress root folder (you may access this file from your WordPress installer folder). From the installation folder, the file is located at wordpress/wp-config.php


Paste the following code to your wp-config.php file, preferably just below every other line of code.


Save and Try updating now. If you have inappropriate directory and file permission, might  encounter upgrade error. Try to do the following-

Web Server Ownership

The first level is actually to make sure that your web server has ownership over the directories:

chown -R www-data:www-data your-wordpress-directory

Directory Permissions

The second level is also required – you must make sure that the directory permissions are properly set:

sudo find /var/www/wordpress/ -type d -exec chmod 755 {} \;
sudo find /var/www/wordpress/ -type f -exec chmod 644 {} \;
