2CheckOut Inline Checkout Crash

Problem

Chrome™ browsers crash with the following error when your customer makes a payment using 2Checkout:

Aw, Snap! Something went wrong while displaying this webpage. Err code RESULT_CODE_KILLED_BAD_MESSAGE

Cause

Your Checkout Style setting in the 2CheckOut module configuration is Inline Checkout.

2Checkout has deprecated the inline checkout style and no longer supports it.

Workaround

To work around this temporarily, ask clients to attempt payment again using a different browser (for example, Firefox®, Opera, or Safari®).

Solution

To resolve this issue:

  1. Go to Configuration () > System Settings > Payment Gateways.
  2. In WHMCS 8.5 and earlier, choose the Manage Existing Gateways tab.
  3. Change Checkout Style from Inline Checkout to Standard Checkout.
    2Checkout configuration in Payment Gateways
  4. Click Save Changes.
