[resolved]how to duplicate flat rate shipping metod ?

I tried two times to duplicate the flat rate shipping module using as example this metod http://forum.opencart.com/viewtopic.php?t=6696 for shipping module only 5 were posible out of 7.
When i want to instal the new flat 2 shipping metod ,i get this error

Fatal error: Class 'ControllerShippingflat2' not found in ......../admin/controller/extension/shipping.php on line 124

if i want to uninstal the new shipping method

Fatal error: Class 'ControllerShippingflat2' not found in ......./admin/controller/extension/shipping.php on line 149

any idea as how i can rezolve the problem?

ps.i use opencart 1.4.9.1

Did you change the first line of /admin/controller/shipping/flat2.php from:
to:
Because I think that's what it's looking for.

FYI you shouldn't have to duplicate flat rate shipping ever

Hello,

I see this has been resolved, but I'm having a problem.

I duplicated the flat shipping module, named it flat2.

I successfully installed it and enabled it, but on the checkout page, it doesn't show; I get stuck at the Delivery Details form, and the Continue button does not do anything.

However, once I disable flat2, the Continue button works as normal.

What could the problem be?
I use OC 1.5.1.3

Thanks in advance.

What could the problem be?

From the duplicated shipping module, the returned key from the array may be invalid which may cause a background error through JSON but you just can't see it straight on the browser which is why when clicking on the continue button, nothing happens on the front-end but, originally, a background error does occur.
