Weathermap Error

[golef]

I seem to be getting an error when the poller runs it does generate the maps and works fine, I am just attempting to figure out the following error.

Warning: key(): Passed variable is not an array or object in C:\Inetpub\wwwroot\
cacti\plugins\weathermap\setup.php on line 457

I did look at the setup.php and I think the problem is the 'times' but I don't know for sure below is the offending line from setup.php.

if( isset( $rrd_update_array{$file}['times'][key($rrd_update_array[$file]['times'])]{$dsname} ) )

Which version of Weathermap is this? (and Cacti, PHP, and OS)

That's a new one to me...

I am running the Catci version of weather map with plug in version 2.1

I'm not sure the error has not been there all along I have been attempting to get the boost plug in working and when I enable it weather map will not generate maps that is when I noticed the error in the poller window.

My cacti installation is running on windows with plug in version 2.1.

But... WHICH version of weathermap? (0.94, 0.95, 0.95a,0.95b?)
and WHICH version of Cacti, PHP etc...

[golef]

Weather Map 0.95B
Cacti 0.8.7b
PHP 5.2.5

Thanks,
