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:

PHP Code:

thrown in /includes/modules/westminster_new/additional_images.php on line 132 
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 Code:
PHP Parse error:  syntax errorunexpected '['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!
