I have file upload enabled here. When I upload an image, I should be able to see the uploaded file in a modal windows I think, by clicking the button next to remove. However, I see the screen turning black, but the image is never shown. Maybe there is a z-index issue here?
popup/modals are being conflicted with some other plugins. in future we may remove this preview box as it has no worth for user to see his own uploaded image 😉
