With activated option for PageListThumbs aos produces a PHP warning in admin tree-view, running PHP 7.2: PHP Warning: count(): Parameter must be an array or an object that implements Countable in .../AdminOnSteroids/AdminOnSteroids.module:3142

This is the case only if the selected imagefield is set to output "single element, null if empty". Would be nice to have this intercepted (I guess it's related to output formatting…?).
