[ka-Map-users] viewport width undefined

[Brent Pedersen]

hi scott, the scales are the same, but the extents are different for the 2
init.php outputs. why is that?

also the url for the broken is: 'http://dev.keystoneresearchmap.org\/'  with
an extra '\' after the org. that might be enough to break it.
