Hello, I'm trying to access yii framework on my lamp which i got along with zurmo crm installation, but i'm not able to access yii framework. I have all the required files and folders. and i'm done with "http://localhost/zurmo/yii/requirements/index.php" it works, and "cd YiiPath/framework" but when i try "./yiic webapp ../testdrive" it shows: Create a Web application under '/var/www/zurmo/yii/testdrive'? (yes|no) [no]:y       mkdir /var/www/zurmo/yii/testdrive PHP Error[2]: mkdir(): Permission denied     in file /var/www/zurmo/yii/framework/console/CConsoleCommand.php at line 456 #0 /var/www/zurmo/yii/framework/console/CConsoleCommand.php(456): mkdir() #1 /var/www/zurmo/yii/framework/console/CConsoleCommand.php(454): WebAppCommand->ensureDirectory() #2 /var/www/zurmo/yii/framework/console/CConsoleCommand.php(365): WebAppCommand->ensureDirectory() #3 /var/www/zurmo/yii/framework/cli/commands/WebAppCommand.php(94): WebAppCommand->copyFiles() #4 /var/www/zurmo/yii/framework/console/CConsoleCommandRunner.php(67): WebAppCommand->run() #5 /var/www/zurmo/yii/framework/console/CConsoleApplication.php(91): CConsoleCommandRunner->run() #6 /var/www/zurmo/yii/framework/base/CApplication.php(169): CConsoleApplication->processRequest() #7 /var/www/zurmo/yii/framework/yiic.php(33): CConsoleApplication->run() #8 /var/www/zurmo/yii/framework/yiic(14): require_once()". And when i try "http://localhost/zurmo/yii/testdrive/index.php" in browser, It shows the error message:Not Found  The requested URL /zurmo/yii/testdrive/index.php was not found on this server. because i dont have "testdrive" folder in "yii". Could somebody please help me to solve the issue and access yii framework...
