问题
There is solution. In my sites on virtuemart I manually (with code editing) do one page checkout (and one step). But after version 3.0.10 my solution no longer work.
Before version 3.0.10 I used follow method:
In cart/tmpl/default.php in bottom of file present hidden inputs.
After <input type='hidden' name='task' value='updatecart'/>
add <input type='hidden' name='task' value='confirm'/>. And it works.
But after version 3.0.10 I found no other option except hack of virtuemart core:
In cart/tmpl/default.php in bottom of file present hidden inputs.
Del <input type='hidden' name='task' value='updatecart'/>
add <input type='hidden' name='task' value='confirm'/>.
In site/components/com_virtuemart/controllers/cart.php
in method display() change
if(($task == 'confirm' or isset($request['confirm'])) and !$cart->getInCheckOut()){
$cart->confirmDone();
to
if(($task == 'confirm' or isset($request['confirm'])) and !$cart->getInCheckOut()){
$cart->checkoutData(false);
$cart->confirmDone();
My English is bad, but hope this will helpful.

There is no need for hacks anymore. VirtueMart 3.0.10 doesn't have double confirmation. Just check "OPC" and "Ajax for OPC" in the VirtueMart configuration - tab "checkout". If you have chosen shipping and payment and checked the TOS button, the "Check Out Now" button switches to "Confirm Purchase". One click and it is done.
Best practise will be to delete your old overrides and use the original VirtueMart files. Apply any custom changes to the new original files.
