    I updated my plugins and then tried to connect my wordpress.com account in order to active Jetpack, and then I got this error:

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘_show_post_preview’ not found or invalid function name in /data/22/3/93/57/3093709/user/3447503/htdocs/wordpress2/wp-includes/plugin.php on line 406

    It’s on all of my admin pages as well as my site pages. I deleted Jetpack from my FTP but it didn’t change anything. And line 406 on my plugin.php page is only an *.

    It also won’t let me access any of my pages in the admin panel, it gives this error: Fatal error: Call to undefined function get_post_format() in /data/22/3/93/57/3093709/user/3447503/htdocs/wordpress2/wp-admin/includes/class-wp-posts-list-table.php on line 551

    Does anyone know how to fix this?
