[gradebook2-dev] Gradebook2 not listing students

[Ramanuja Chary, Vijayarengan]

Hi Gradebook2 developers

We are unable to view the student list in Gradebook page. 

But the site info shows the student list properly and their Status are active.

Please do let me know, if you need more information to locate the source of error.

Thanks
