All is displaying except one post

Hi!

First of all, my appreciation for this very useful plug-in The Post Grid. I find it is very useful to use and it displays posts beautifully.

All has been working fine with this plug-in on my website, until yesterday when, for some reason, the plug-in decided not to display this one post only. So, all other posts are displayed just fine, but only this one isn’t. It appears in the plug-in preview though.

If anyone has a suggestion for solving this mystery, I would be thankful.
