Hi--

We have a problem on our nop commerce 3.5 install. The View loads fine, but whenever you change anything you get an error saying 'not found. please contact the store owner.' When I look in the system log I see errors:

  A public action method 'updatepaymentmethod' was not found on controller 'SevenSpikes.Nop.Plugins.RealOnePageCheckout.Controllers.RealOnePageCheckoutController'.  8/3/2015 2:30:01 PM  View
  Error  A public action method 'updateshippingmethod' was not found on controller 'SevenSpikes.Nop.Plugins.RealOnePageCheckout.Controllers.RealOnePageCheckoutController'.  8/3/2015 2:27:47 PM  View

  Error  A public action method 'updateshippingmethod' was not found on controller 'SevenSpikes.Nop.Plugins.RealOnePageCheckout.Controllers.RealOnePageCheckoutController'.  

I tried to peek inside the dll to see if those methods were there, but it looks to be obfuscated so I hit a brick wall. I'm setting up a sandbox in my development environment to see if its something wrong with my env on the server, but wondering if this is something super simple I'm missing. Let me know if any further information is needed to get help.
