Backtrace from Warning – Undefined property – WP_Query

I have a development site at:
http://acquireb2bdev.com/resources/data-sheets

I’m getting several errors and warnings from Lightbox Plus Colorbox and I’m trying to resolve them all in the hopes of making the site more stable.

<p>
Backtrace from warning ‘

A forum member pointed these warnings out. Perhaps someone has an idea of how to resolve them or the developers could assist.

Thanks for your help.
