Not possible to preview imagens on the media panel
When creating/editing an article, it is not possible to preview images on the media panel.
To repeat the bug:
- Upload an image
- Create an article, or edit an existing one
- Expand the media panel ("Insert media [Show/Hide]"
- Click on the "Zoom in" icon that is displayed when you hover on one of the images
If you check the server log, you will find an internal error.
