error in categories with v1.3

Hi,

I’m getting this error on any category with no access restriction set..

Warning: in_array() expects parameter 2 to be array, null given in ……..\wp-content\plugins\groups-restrict-categories\lib\admin\class-groups-restrict-categories-taxonomy-admin.php on line 455

if I add a capability it goes away..

however, obviously I don’t want to restrict every category, so I guess this needs fixed..

tags has the same error too..

please advise,

thanks..

I have groups 1.5.3 and restrict categories 1.3.0 versions activated.
