I have imported PHPExcel into /protected/extensions/phpexcel, followed all the steps. Created an action to call the createExcel action.
But I get this error:
Fatal error: Class 'Controller' not found in F:\xampp\htdocs...\protected\controllers\SiteController.php on line 4
Fatal error: Class 'CListIterator' not found in F:\xampp\htdocs\yii\framework\collections\CList.php on line 90
It was actually generating and working fine the day before. No changes were made to any file the next day. Suddenly this error shows up.
Can I know what may cause the problem?
