Adding payment modules
The PayZen payment module can be added in two ways:
The first method consists in adding the payment module via the WordPress Back Office.
In the Back Office of your WordPress shop, go to the Extensions menu and click on Add.
Select Add an extension, click on Select a file and search for the PayZen_WooCommerce_2.x_v1.2.3.zip file on your hard drive.
Then click on Install now.
The second method consists in copying the module via FTP. To do this, copy the WooCommerce-PayZen folder into the /wp-content/plugins/ of your website.
Once the module is installed, click on Activate to activate the module (Extensions / Installed extensions).
