In case you want to install Prestashop through Plesk, follow the steps described below.
5. Select the location where you want to install Prestashop. If you want the root folder, leave the field to the right of the site blank. If you want a specific subfolder, simply indicate it in the empty field to the right of the site.
a) Select Automatically update this app when updates are available if you want Prestashop to update automatically when it is available.
ATTENTION: In case of automatic update, there may be incompatibility in plugins / themes and therefore a malfunction on your site, so we recommend you not to select it. Besides, Plesk informs you whenever an update is available.
b) In Administrative Access, you choose whether you want to connect to the Prestashop administration with the credentials you have for Plesk or create new credentials from there.
6. In the Main configuration category during installation, Plesk automatically declares some fields. Modify them as you wish and select Install to complete the installation.
NOTE: Through automatic installation, Plesk creates the database and configuration file, so you don't need to do anything extra.
