Hi! I have finally managed to start my first project in ProcessWire. Loving the simplicity and flexibility but I have stumbled upon a problem with Image field. It just does not upload anything. What happens is: Upload progress bar is going up to 100%. Folders in assets/files are properly created, with permissions set to 777. Unfortunately, no image is being uploaded as there are no files in created folders. Nothing shows in Javascript console (Chrome and Firefox), so it is not a front-end
