oc 2 is working sweet, but! secure trading gives me problems....
takes me through the process but after its straight back home to my site and the cart is still full.

Fatal error: Call to undefined method Controllerpaymentsecuretrading::render() in /var/www/vhosts/mysite.com/httpdocs/catalog/controller/payment/securetrading.php on line 166

Fatal error: Call to a member function get() on a non-object in /var/www/vhosts/mmysite.com/httpdocs/index.php on line 97


its like a redirect error...

please help

should you have a redirect error with opencart V2 and secure trading here are 2 files to try:
/var/www/vhosts/yoursite.com/httpdocs/catalog/model/payment/securetrading_pp.php

Remember back up the files your changing, don't mix them up as they are called the same.

the second file is:
/var/www/vhosts/yoursite.com/httpdocs/catalog/controller/payment/securetrading_pp.php


first update your redirect using myst to: http://yoursite.com/index.php?route=checkout/success

you don't need any customfields so remove sid.

This worked for me as 7/11/14. Securetrading and the 3rd party working with open car have said they will look into up dating the files.
