For the WordPress system Timely update maintenance is very necessary to operate, update maintenance can not only update the system service functions, but also to improve the security system.
If you are a user of a virtual host, you can use the FTP account for automatic Update service, but if you are a VPS user, I do not recommend you to open the FTP background service, but it is recommended that you use the manual upgrade operation to ensure the security of the server.
The manual upgrade of the WordPress system is very simple and is divided into the following steps:
1. Download the latest installation package Link
2. Remove the wp-content directory from the installation package,wp-admin/install.php,wp-admin/install-helper.php
3. Re-zip all the files and upload them to the remote directory for a full replacement decompression operation.
