I had a wordpress installed and all was working fine for a few months. Then for no apparent reason, when i am trying to upload images (either by dragging them from desktop to media gallery, or, the conventional file uploader) the file seems to upload, but then it greys out and a preview/thumb of the image is not visible in the gallery. If i select to insert into a post it shows the small error square icon in the place where the image would normally go, within the post.
I deleted the entire wordpress and installed wordpress again, but I still have the same issue.
Any help appreciated. Nic.
