Only this way working well (not simple)
-Log into your cPanel dashboard. -Find the Databases category and click on the phpMyAdmin icon. - Once inside the phpMyAdmin tool, click on the Databases tab. This brings up a list of databases in your account. Click on the name of your PrestaShop database. - Once you select the database the screen will list all of the tables. - Scroll down and click on the ps_configuration table. - The new screen displays all the rows in the ps_configuration table. Scroll down and click on theValue column (the 5th one) of the PS_SHOP_NAME row. In the default PrestaShop 1.6 database, this is row number 235. The value column has the current shop name in it. - The column will allow you to edit the name of the shop. Enter the new name and click Enter. - Once the database tables appear on the screen, look to the tabs at the top of the screen and click on the SQL tab. - This brings you a blank SQL Query screen where you can enter and run your query. The specific query you need to run is below. The only thing you need to change is "New Shop Name". Change that to be your desired store name, be sure to keep the quotes around the name (UPDATE ps_configuration SET value = "New Shop Name" WHERE name ="PS_SHOP_NAME").
- Once entered, click on the Go button in the lower right corner. Once the query runs you should get a success message at the top of the screen.
