I found this URL
http://www.2checkout.com/community/blog/kn...-shopping-cart/
Which says "This module is absolutely necessary to be compliant with our V2 system."


But then there are other articles there that say it works out of the box.


Also I installed the pm2checkout module but in admin modules payment there is nothing saying "pm2checkout" so i cant install it. I can only see 2checkout module that was there before i installed it

Please help

IF you have oscommerce RC2a then no you dont need to install it...

If you have an older version than MS2.2 060817

You will need to download and install the pm2checkout module

Depending on which module you download the title in the admin will not necessarily be 2checkout , you can open the langauge file in the install package to see what the title is.
