I'm setting up a site using the subsites module.
On the main site when I upload an image using the standard UploadField class it shows up in the asset manager. However, when I upload an image in the same way on one of the subsites it doesn't show up in the asset manager.
The uploaded file can be found in the assets/Uploads folder and I can see that it's been added to the Files table in the database, but it's just not being displayed in the asset manager. I can also get the images to display in the front-end templates without any problems.
