error loading General Options when no settings are selected

Fresh installation: error on the settings>NextGen 3D Slider page; every checkbox has the description “Warning: in_array() expects parameter 2 to be array, string given in nextgen-3d-flux-slider-template/admin-settings.php on line xx”

As soon as any checkbox is ticked and the setting saved, the settings page will display normally.

By the way i have spent 2 days to research and install a slider plugin with 3D effects; this is the first one which worked out of the box. Thank you for making this!
