I have encountered and a problem with GoDaddy when running Yii application on the server. On the local machine, everything run smoothly for the Yii application. However, after I transfer the Yii application to Godaddy web hosting, I encountered the "500 (Internal Server Error)" when trying to visit the Yii application, no other information about the error is given. The error goes away after I set the permission for the Yii application's "assets" and "protected/runtime" to Read/Write.
During testing, i found another possible source of code errors that may cause the "500 (Internal Server Error)", which is when the developer does not specify the correct database host name when configure the protected/config/main.php
When the "500 (Internal Server Error)" happened on GoDaddy for Yii application, the best way to discover the error is to examine the protected/runtime/application.log, which may log the error.
