PrestaShop v1.6 Installation Guide

Last Updated: Mar 06, 2017 01:09PM CST
The following is needed before you get started:

PHP 5.2 or later
MySQL 5.0 or later
Access to your FTP server or your MySQL database 
At least Internet Explorer 9 or preferably the latest versions of Chrome/Firefox/Safari or other modern browsers.

This guide assumes that Prestashop has already been installed. If it has not been installed there is a guide on how to do it here

Installation Steps

1. At the moment, the Simplify plugin is not bundled with PrestaShop. For the most up-to-date version of the plugin, download the source code here

2. A registered account on the PrestaShop addons marketplace is needed in order to download this.

3. Extract the Zip file that gets downloaded and move the extracted folder to the following location in the PrestaShop directory: prestashop → modules where all of the other PrestaShop modules are located. 

4. Log in to the PrestaShop admin page, go to Modules and Services section and search for Simplify. The Simplify Commerce link should appear with an install button as shown below.

5. Once the install is successful, the install button should change to Configure 

6. Click on Configure and it will open up the setup screen.

7. The configuration page above contains the following:

API Key Mode - This is set as Test Mode by default, when ready to go Live, change it to Live Mode.
Set Your API keys - They can be found here on the Simplify Commerce account that is going to be used (you might want to create a new key pair specifically for PrestaShop):


Live Public Key – This is the live key found on the API Keys section for live payments.
Live Private Key – This is the live key found on the API Keys section for live payments.
Test Public Key – (Test Mode) – Sandbox must be enabled to use this field.
Test Private Key – (Test Mode) – Sandbox must be enabled to use this field.

Save Customer Details - Allows the customer to save their details so the next time they want to purchase something they wont need the card details.

Payment Mode – Two options on how the card form should appear.

Standard – The card field appears on the checkout page.
Hosted Payments – Hosted Payments must be enabled in the simplify API Keys settings.
With SSL –  A modal dialog will appear on the checkout page.
Without SSL – Customers are redirected to Simplify's Commerce's secure site to pay. 

Modal Colour – Only available when Hosted Payments is selected above in Payment Mode.

8. Once all of these settings and API keys are configured, click the save button to commit the changes.

9. The plugin can be enabled and disabled by clicking on the drop down beside the configure button on the Modules page. 

Possible Pitfalls

If Simplify is not appearing on the checkout page, it may be an issue with SSL. The grade of the SSL can be tested on by entering in the main website address. That page will report some of the issues with the SSL setup.

If there is an API error being received, it should be checked that the correct Public & Private Keys have been input (not test keys) and that Test Mode is disabled.

If there are difficulties arising with the version of PrestaShop running and need to reinstall, the guide can be found here:
