Magento 1.9 – Fix DHL Shipping Method Unavailable Issue

I found the "steps to reproduce" and hotfix. Originally we enabled the "Website Payments Standard" payment method and then disabled because we had the problem with "Suspect Fraud" status. Immediately after I disabled the "Website Payments Standard" it turned into "Website Payments Standard (Includes Express Checkout)" and I was not able to revert it back. This behaviour is always reproducible on Magento CE 1.9.1.0

I found out that if I enable the payment method directly in database, it reverts back to the "Website Payments Standard".

This is the query to re-enable it:

update core_config_data 
set value = '1' 
where path = 'payment/paypal_standard/active';

I am not sure why it behaves like that and we have not enable it on production yet because we are still trying to solve the "Suspect Fraud" status problem. We discovered that some of the modules we installed are causing conflicting (Stored Credits, Payment Charge etc) and thus charging incorrect amounts, but that is different story.

We have had the exact same error. Flow is like :

• Magento cart
• In cart click paypal express
• Click ok continue etc paypal
• Return to Magento paypal/express/review page (template/paypal/express/review.phtml)

case

a. If I set no shipping method and click continue I see the error "Please specify a shipping method"

b. If a shipping method is prepopulated thus the select element is set and I only click continue I see the error "Please specify a shipping method"

c. If we set the select element through JS to a default vallue only if it is unset even then I see the error "Please specify a shipping method"

ridiculous fix

It is an almost ridiculous fix, but it works. We added the following code to force the select value to a certain default if empty, and even if already on the default value. After that we trigger the updateshippingmethod button click and submit.

Actual problem

The only problem we actually had was that - coming back from Paypal the Shipping Method was empty and users needed to select a shipping method. The problem was that customers clicked CONTINUE like 10 times before they noticed the error (or abandoned) - So we decided to auto-set a default shipping method. Only this 'setting' of the default shipping method does somehow not transfer to the quote

I am very open to alternative fixes

Fix

<script type="text/javascript">
    //<![CDATA[
    // submit buttons are not needed when submitting with ajax
    $('review_submit').hide();
    if ($('update_shipping_method_submit')) {
        $('update_shipping_method_submit').hide();
    }

        var selectThis = 'postnl_matrixrate';
        var ppcookieName = 'paypalexpress';
        var selectOption = $("shipping_method").getValue();
        var selectCookie = Mage.Cookies.get(ppcookieName);
        if ((selectOption == '' || selectOption == selectThis) && !selectCookie) {
            $$('select#shipping_method option').each(function(o) {
                if(o.readAttribute('value') == selectThis) { // note, this compares strings
                    o.selected = true;
                    Mage.Cookies.set(ppcookieName,'clicked');
                    $('update_shipping_method_submit').click();
                    // throw $break; // remove this if it's a multi-select
                }
            });
        }

    <?php if ($this->getUseAjax()):?>
    OrderReviewController.prototype._submitOrder = function() {
        <?php /** SNH CUSTOM 7-9-2018 Need to trigger a button click here to respect the pre-selected shipping method **/?>

        $('update_shipping_method_submit').click();
