Why do I see the blank page instead of order details in backend?

[chien_vu]

when order's status is new, it still show

when order's status is complete or delivering, it doesn't show

Please let me know how to solve this issue. Thank you!

Kindly check your system.log file for error of your ordre page,

Go to Magento root instance with var/log folder and edit system.log file to check any critical error exist or not.
