No Grid Lines

[admin]

Most likely your browser has been zoomed in - some browser's will lose grid lines at zoom levels other than 100%.

To reset your browser zoom level:

Press Ctrl (Windows) or Command (Mac) and the 0 key

I have been playing this game all day suddenly I lost the grid lines so cannot see the boxes. Have rebooted computer and logged in again and still no grid lines on any level on this game.
Any suggestions on how to get them back
