Never mind, I have resolved the issue. Issue is caused by some third party plugins mod_exagames which I have installed in Moodle. The way I troubleshoot this is to first set the Development --> Debugging --> Debugging message to Developer mode. So that I will be able to see more errors in details. Then, when I click on the Scales, it displays more information on the error, in which one of them is pointing to the files in exagames mod. As I suspect that may be the cause, I go ahead to uninstall that plugin, and finally I am able to access my Scales with no more error shown. Somehow that plugin clashes with the Scales. Hope this will help whoever have the same problem as mine.
