I can no longer see the text on a document I'm editing!

It's like it's hidden behind white blocks. A1 right through to D5 below all have text in them, but I can only see it in the top edit bar, not the cells themselves. Any ideas?

Update - it now looks like this.

Try Clear Formats and see if all of the data is there. Looks to me like Formatting issue.

Also try pressing
F5 -> Special... -> Objects -> OK
and see if anything gets selected or you get a message "No objects found"
