I have just deactivated the NextGen Gallary plugin since after I installed it it produces an error when using
$content = apply_filters('the_content', $post["post_content"]);
Notice: Trying to get property of non-object in \wp-includes\post-template.php on line 30
After deactivating the plugin i started to work properly again so I'm a little bit confused. Anyone know where to start debugging it?
