Give this a shot: <a href="http://pastie.org/2270372" rel="nofollow">http://pastie.org/2270372</a> </p> https://legacy.forums.gravityhelp.com/topic/fatal-error-when-using-the_post_thumbnail-code-snippet#post-30915 Mon, 25 Jul 2011 15:57:42 +0000 morality28 30915@https://legacy.forums.gravityhelp.com/ <p>Hi - I tried the solution from this post <a href="http://www.gravityhelp.com/forums/topic/auto-setting-the-the_post_thumbnail?" rel="nofollow">http://www.gravityhelp.com/forums/topic/auto-setting-the-the_post_thumbnail?</a> to auto set the image uploaded to be the featured image. When I do, it crashes my theme and says that the_post_thumbnail is already defined in my wp-includes folder in the page.php file. When I browse my wp-includes folder I don't even see a page.php file, which is odd.</p> <p>Is this fatal error something to do with my theme do you think? And how could I go about getting this piece of code to take in my functions.php file?</p> <p>Thanks! </p>
