I have a problem with the media uploader in that when I upload any image to WordPress the system behaves as you would expect but displays blank images (thumbnails and full size).
When you view the images the system obviously knows they exist and their size properties, but nothing is displayed bar the 'image holder' icon.
I've tried uploading both PNG and JPEG formats. Both were optimised.
This is disabling all work on the site
Thanks in advance for any help.
