Php 5.6 To Php 7.0 Upgrade Issue

Hi,
I am using CS-Cart 4.9.2
it works fine witith the PHP 5.6
Unfortunately, when I switch the PHP to PHP 7.0, i get the front end errors:

PHP Warning
Message

array_combine(): Both parameters should have an equal number of elements
Error at

app/functions/fn.common.php, line: 5808

and backend errors:

Message
array_combine(): Both parameters should have an equal number of elements
Error at
app/functions/fn.common.php, line: 5808
Did anybody anybody encountered this?

Kind regards

Please make sure that the app/functions/fn.common.php file is not modified in your installation. There is no array_combine function on this line in version 4.9.2. You can use the File changes detector to check the installation files
