PHP Weathermap and Cacti 0.8.7 not updating links

[shess]

'm running 0.97a php weathermap on a Cacti 0.8.7.f machine with 1 minute polling. I've got cacti polling and graphing just fine but when Weathermap runs it gives the following error for any RRD and won't update the link info:

WARNING: weathermap.conf: ReadData: RRA NAME had no valid data, according to WeatherMapDataSource_rrd


There is valid data there but weathermap doesn't seem to want to read it. Below is an RRDTOOL info on one of the RRD's. Weathermap does work because if I bring in an RRD from another cacti box (doing 5 minute polling) it will display data for the link. What am I missing?
