Fatal PHP error after upgrading to PHP 7 : [] operator not supported ...

[mhmdshv]

Hi,

I've recently updated the PHP version of my host to 7.1. Everything went fine except my prestashop installation. I'm using prestashop 1.6, and the below message is shown in the error log:

PHP Fatal error:  Uncaught Error: [] operator not supported for strings in 
	C:\\prestashop\\classes\\db\\DbQuery.php:70\nStack trace:\n#0 
	C:\\prestashop\\classes\\ObjectModel.php(203): DbQueryCore->from('shop', 'a')\n#1 
	C:\\prestashop\\classes\\shop\\Shop.php(131): ObjectModelCore->__construct('1', NULL, NULL)\n#2 
	C:\\prestashop\\classes\\shop\\Shop.php(392): ShopCore->__construct('1')\n#3 
	C:\\prestashop\\config\\config.inc.php(97): ShopCore::initialize()\n#4 
	C:\\prestashop\\index.php(27): require('C:\\\\prestashop\\\\m...')\n#5 {main}\n  thrown in 
	C:\\prestashop\\classes\\db\\DbQuery.php on line 70

It appears that prestashop is trying to append an array item to a string in its core files. Is there any solution to this problem?

I'm on windows server 2008 R2, running PHP 7.1, MySQL 5.7, and Apache 2.4

Thanks are in orders.
