Fatal error, resolved by clearing Pod Cache

[jessicaperry]

Re-posting this from forum to here:

The following error keeps showing up intermittently on my site (for some pages, but not others, and never for the same page).

Fatal error: is_callable(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "PodsField_Pick" of the object you are trying to operate on was loaded before unserialize() gets called or provide a __autoload() function to load the class definition in /home/deer/public_html/wp-content/plugins/pods/classes/fields/pick.php on line 1377

If I go and clear the Pod Cache (Pods Admin > Settings > Clear Pods Cache), it fixes the issue. However, several days later, the error shows up on another page.

Most recently, it showed up on: http://wyocoopunit.org/people/jenny-jones

Settings below. No, I don't have a copy of the site, unfortunately.

I doubt it's the version of PHP, but that might be an issue. Can you look into upgrading your PHP on this particular web server?
