My cache directory is set to 777
I have GD installed
I have PHP 5.3.19
$instance['thumbnail']['active'] does not returns true.
Most likely It has to return true in order to show the thumbnail. What do I have to do? I am not using the sidebar widget, I am using the template tag. I set it from admin to take the first image from the post. No image is showing, not even the default one.
