First, you need to log in to your account through SSH.
By default you'll be logged in the directory /home/username (where username is replaced by your actual username).
So, if your php BB3 site is installed in a folder called phpbb3 in the root public_html directory of your account, the URL address should look like this: yourdomain.com/phpbb3/install/database_
After the database is updated you can delete the install folder and the patch file from the root php BB3 directory on your account.
In this tutorial we'll assume that your php BB3 application is installed in a folder called phpbb3 in the public_html directory on your account, which means that the path to it would be /home/username/public_html/phpbb3.
The command that you have to execute to upgrade your application looks like this: with the actual paths.
The first thing you have to do is to go to the download section of the official php BB3 site and download the patch files archive.
It contains several patch files corresponding to different php BB3 versions.
You can do this by opening with your internet browser the URL address of the database_file that's inside the install folder you uploaded earlier, before starting the upgrade.
After you download the archive you have to unpack it on your local computer and then upload the install folder and the corresponding patch file to the root php BB3 directory on your hosting account (e.g.
public_html/phpbb3) with an FTP client or through SSH.
