Warnings in class-utils.php

Hi,

under “Customizing -> Content -> Blog Design and Content -> Display the featured posts also in the list of posts” there are two warnings displayed. Not sure how important this is, but I thought it’s better to report it:

Warning: Illegal offset type in isset or empty in /…/hueman/functions/class-utils.php on line 250

Warning: Illegal offset type in isset or empty in /…/hueman/functions/class-utils.php on line 256
/>

The checkbox was originally selected but the posts weren’t displayed. I deselected and re-selected it, which made the posts re-appear and from my perspective all works fine. The warnings are still displayed, though.

Please advice if I need to do anything on my side or is this a real bug needing fixing.

Best regards.
