> Problem:
> The variable $cfg['keys'] is treated as an array but can be an empty string.
> When treating the variable as an array it is not checked if the variable is
> indeed an array. 
> 
> Solution:
> Check if $cfg['keys'] is an array before running it through foreach.
> 
> Comments:
> See attached patch.
