 * I enabled debug mode in WordPress about a week ago and have been watching the
   file since then. In a week it’s logged 16 errors, all the same. Here’s the error.
 * PHP Warning: Invalid argument supplied for foreach() in /home/customer/www/trinityfort.
   org/public_html/wp-content/plugins/post-grid/includes/post-grid-layout-elements.
   php on line 2921
 * Any idea what’s causing this?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fphp-warning-342%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Thanks for your post,
 * Please select at least one media source if you added a media element to the layout.

 * Both of the layouts we are using have no need for an image, so I removed it from
   the layout. I’ll keep an eye on the debug file. Thanks for your help!
