Cannot open word documents in e-mail on iPhone 6 Plus

I am having an issue opening my word documents on my iPhone 6 Plus and iPad. I am not sure if this has something to do with iOS 8 or not. I was always able to open my documents in email before, but now I cannot. I have tried deleting and re-entering my email account, I have also tried installing a document reader, this did not work either.

Hope someone can help.
