When attempting to change/add a flag while in tools/google maps/geographic data an error is thrown. Tested on 2 live sites and 1 local wamp site. Got the same error on your 3.0 beta test site. The error reads:
“Fatal error: Call to undefined method WT_Stats::getAllCountries() in C:\xxxx\xxxx\kiwitree\modules_v3\googlemap\module.php on line 430.”
On your 3.0 beta site the line number is 424.
The flag files are in the proper folder; at least on my sites.
Worked fine on ver 2.0.
Should a bug report be filed?
