Wrong language on Paypal Express Checkout since upgrade to v1.54.

Finally did the upgrade from 1.39h to 1.54, which seems to working ok so far apart from a few niggles:

1. Paypal Express Checkout now defaults to German language even if browser and shop are set to English. I tested this also with a UK proxy and it still came up in German.
   I've set Configuration/Mystore/Language Selector to Browser, and wanted to tweak the paypalwpp.php file as for v1.39 but this file for v1.54 is very different so I've no idea where to start.

How can I get Paypal to always use the browser/ shop language?

2. Paypal Express checkout no longer displays product names & information, only the total cost.

Any input would be greatly appreciated.
Thanks

Have seen something similar to this before:
What languages are installed and what are their id numbers?
What are all of your paypal express settings (obviously don't include credentials)?
What are your settings in modules order totals, including the which are green and their sort order?

Thank you mc12345678 for your response.

Only default English plus german language installed. Not sure what you mean by id nos?

The frustrating thing for me is that I had this language issue before in v1.39h which was resolved by this fix from DrByte https://www.zen-cart.com/showthread.php?106924-PayPal-Express-Checkout-Default-Language.

Going to take a lap through the proposed previous fix (though think the ONLY EUR is probably the cause), but to address the single total only, if not mistaken need to include the sub-total in order to show each product individually and also in order before the total.

Any other offers?

please!

Given that my testing environment for this is limited, I haven't tested this thoroughly, but I'm offering it as an idea.

Around line 1004 in the paypalwpp.php file you'll see the following section of code.
I'm suggesting adding the highlighted changes as shown:

    $lang_code = '';
    $user_locale_info = array();
    [B]global $lng;[/B]
[B]    $user_locale_info[] = $lng->get_browser_language();[/B]
    if (isset($locales) && is_array($locales)) {
      [B]array_push($user_locale_info, $locales);[/B]
    }

Actually, my previous post was wrong.
This works better:

    $lang_code = '';
    $user_locale_info = array();
    if (isset($locales) && is_array($locales)) {
      $user_locale_info = $locales;
    }
[B]    global $lng;
    array_unshift($user_locale_info, $lng->get_browser_language());
[/B]    $user_locale_info[] = strtoupper($_SESSION['languages_code']);

My Zencart is 1.54. I faced the same problem. After I edited the paypalwpp.php as mentioned in your post, the customer cannot land on Paypal login page any more after he confirms the order. Is there any further solution to this? 

Thank you!
