User Guide

 /config folders, only copy the settings.inc.php file, then modify the
following lines:
o The line that contains "PS_BASE_URI" must contain the name of
the subfolder where you are going to do your update. For
instance, "/prestashop/" instead of "/", or of the name of
current folder for your current store.
o If you modified your database credentials (you should not
have had to do that normally), update all the lines that
contain "DB_NAME", "DB_USER" and "DB_PASSWD" too.
Moving the "prestashop" folder to your FTP server
The "prestashop" folder that you have unzipped, now contains all the
modifications from your "Backup" folder (and therefore, from your current
live store). This next step will have you upload that folder on your FTP
server.
Caution
If the folder of your online store is already named "prestashop", rename
the "prestashop" folder on your hard drive to something else before
sending it onto your FTP server.
If you renamed the "prestashop" folder, do not forget to update the
config/settings.inc.php file accordingly, as explained in step 2-B.
Using your FTP client, upload the "prestashop" folder to your server.
