PHP Parse error: syntax error, unexpected '[' in paypalwpp.php

Hi there,

I am running into some problem at checkout. I think I should upgrade the PHP version, which I did yesterday to V.7.1 but that caused more problems, and I wasn't able to view product in single product page:

So, I rolled back to PHP7 instead, and while I am now able to add items to cart, but when checking out, it hits a blank page, and my log shows this error message:

PHP Parse error:  syntax error, unexpected '[', expecting ',' or ';' in /includes/modules/payment/paypalwpp.php on line 1148 

I am preparing for my finals, so I can't do anything major such as upgrading my cart from v1.5.4p1 to most current version or upgrade the template. Is there a temporary fix that I can use for now?

Thanks in advance!

ZC v1.5.4p1
PHP 7.0
Template: westminster_new

Zen Cart 1.5.4 was not designed to run on PHP versions > 5.6, as your debug-logs indicate.

Line 1148 of paypalwpp.php, for instance, contains

          global $$order_totals[$i]['code'];

On PHP versions > 5.6, that "runs into" the change to indirect variables (aka variable variables), as described here:

http://php.net/manual/en/migration70.incompatible.php

Try changing your PHP version to a variant of 5.6! (Upgrading Zen Cart is a wise idea too)
