User Map

Hi,

I'm using the gmap module for generating a map of user locations, but I'm getting a weird error on the map. It says :

warning: array_intersect() [function.array-intersect]: Argument #1 is not an array in /var/www/html/cms.projectpier.org/sites/all/modules/gmap/gmap_location.module on line 96.

Can any offer some help? I noticed in the locations table there were some errors with lat/long = 0.0, so I deleted them hoping it might clear up the problem but no luck.
