Hi Zen Members,

I have installed thed latest zen cart on my site. My website can be found at: http://researchkart.com/zc
I wanted to integrate CCAvenue World Account (USD Account) to my zen cart theme.

For the same, I had used the latest plugin from the below link:
http://www.zen-cart.com/downloads.php?do=file&id=717

All is installed as suggested and I have changed the setting as indicated from the read-me file provided.

But, I am getting Error page from CCAvenue "Error 90".

Can anyone share if I have used the correct plugin or please assist me on this issue?

Please find below the snapshot of the error i get when we click on final checkout button
