array_keys() error

I tried to filter out the options to insert a view into a node, in the node edit form. This created the following error for roles other than admin:

warning: array_keys() [function.array-keys]: The first argument should be an array in \sites\all\modules\formfilter\formfilter.module on line 88.
warning: Invalid argument supplied for foreach() in \sites\all\modules\formfilter\formfilter.module on line 88.

I unfiltered the components of the form, problem still exists.
Help please.

Thanks

Glenn
