WooCommerce and Paypal for WooCommerce Plugin

[localsaver]

I'm trying to choose a WP plugin so that i can received credit cards from paypal & non-paypal customers.  

I already have Paypal Here setup on my Ipad, and I have a Business/Merchant account with Paypal currently.  

I'd like to set up Paypal to work on my website.  I'm not sure which would be the best plugin to use.  I'm looking at the Paypal for WooCommerce plugin right now.  It asks about what version of PayPal Pro (2.0 or 3.0) that I have. Not sure about that info, and if this is the best plug-in to use.  Need something simple, because I'm newbie at the WP programming, etc.

I am getting the same error message as well. My paypal manager account is set up as well.

@gosimplypro what error are you getting exactly?

[gosimplypro]

There was an error processing your order - User authentication failed

Do you have values filled for all 4 credentials?  user, pass, vendor, partner?  

If not, you need to use the same value for user as you do for vendor.  Give that a shot and let me know if that helps.
