problem with single user unable to upload -white page
I have 37,000+ users, none have issues except for one. It is a strange one.. on my pc logged in as him all is fine. On his pc IE or Firefox.. it chugs, then he gets a white page. We've gone through a lot of steps such as disabled any apps that might be interfering, clearing cache & cookies, trying different areas to place the original image. I'm stumped.. any ideas? Thanks!
