But we were required to use separated development environment,not xampp-integrated development environment.
I installed piwik1.3,this is still have this problem: unforeseen circumstances,request occur during the problem,please try it again.
From the zh-cn.php, I fond this was “General_ErrorRequest”.
Did I really need to update my development environment?
The piwik1.4 did not asks for install environment. and before installing ,it had checked the environment.
