So I can see the attachement when viewing the post as a single. But it is not there in the instance on the admin edit screen.
In another post, I have added an attachment on the admin edit screen, but it is not showing up on the post.
This might be because i had attachements installed, then I though we could work without it, so I took the section out of the the function.php file and deactivated the plugin.
Now we have decided that attachments will work with our content and I have re-installed the section in the function.php and reactivated.
So I think I have one little confused website.
Any clues where I might look to solve this.
