when enabled against the latest dev version of Commerce I get
Notice: Undefined index: ipn_logging in commerce_paypal_wps_settings_form() (line 89 of D:\xampp\htdocs\d7commerce02\sites\all\modules\commerce_paypal\modules\wps\commerce_paypal_wps.module).

kthullI encountered the same error, then I noticed that neither option was checked under IPN logging on the PayPal WPS configuration screen. When I chose either option, that error message went away.

rszrama commentedAs far as I can see, this has been fixed by properly initializing the default settings. I don't get this error on a current install of the module.
