I am new to Yii and have to work on a project that involves a legacy Yii application. I am not sure which version of Yii framework was used to code the application. I am trying to setup the website without a configuration document and came across several issues. Appreciate if you can help answer my questions below:
How do I find which version of Yii framework has been used to write the application? What steps do I need to follow to migrate from an old yii version to a new version?
I checked the application log and I found the following issues which I am not sure how to resolve -
a. [error] [exception.CHttpException.404] exception ‘CHttpException’ with message ‘The system is unable to find the requested action “GetCPInfo”.’ in /var/www/yii/framework/web/CController.php:484
b. [error] [php] Use of undefined constant id - assumed ‘id’
