Post-upgrade problems: Image URL in DB, but not showing

I don’t have time to produce working code for this. I will edit the answer if I get the chance. In the meantime, you probably want a filter on upload_dir to alter that path. Your code would look something like this then: function alter_upload_wpse_107016($upload) { remove_filter(‘upload_dir’,’alter_upload_wpse_107016′); // alter $upload array return $upload; } if (1 … Read more
