I'm using Magento 1.8.1.0 to run my store,I have installed the 2checkout payment gateway extension [http://www.magentocommerce.com/magento-connect/2checkout-payment-extension.html] and made the required account configurations
The problem is when I set the compilation mode to disable the 2checkout payment option works fine at the checkout page. but when I try to switch the mode back into enable the 2checkout option disappears?
I have contacted both Magento, and 2checkout company to tell them about this issue. but everyone says this bug happens by the other side.
Did you know how to fix this ? and what if I kept the compilation mode disabled. does it effect any thing in my store?
