PrestaShop is very easy to uninstall:
- 1.Delete all of PrestaShop's files and folders on your web server, using your FTP client.
- 2.Delete all the
ps_tables from PrestaShop's database, using phpMyAdmin.
You will lose all information registered to your store: customers, orders, invoices, products, etc. This cannot be undone unless you have proper backups of all your data.
