Does the media uploader work fine when Gravity Forms is disabled? I am not sure how these two things would conflict, as we haven't had any conflicts in the recent past with any vanilla WordPress features.</p> <p>Are you using the Twenty Eleven theme? If not, can you try that as well, with Gravity Forms enabled. </p> https://legacy.forums.gravityhelp.com/topic/gravity-forms-causing-error-with-media-uploader#post-77648 Thu, 27 Sep 2012 10:16:45 +0000 Stewarty 77648@https://legacy.forums.gravityhelp.com/ <p>Hi There,</p> <p>I've found an issue where it seems that Gravity Forms is causing the Upload New Media action of the admin panel to fail.</p> <p>When the plugin is active Trying to upload media through the media manger fails with the error. </p> <blockquote><p>Cannot redeclare create_initial_post_types() in /Users/stewartritchie/Dropbox/Sites/LLHP/wp-includes/post.php on line 19" </p></blockquote> <p>(Local dev environment)</p> <p>From what I can tell it seems that something in Gravity Forms is telling PHP to include '/wp-includes/post.php' when it clearly has already been included, but I can't find it anywhere!</p> <p>To make this slightly worse it appears to happen randomly, two or three uploads will go through fine then the error happens, after that all fail.</p> <p>Gravity forms is currently the only plugin active. </p>
