‘Internal server error occurred’ when clicking into "Dashboard" and "Analytics" tabs

Hello everybody,
I installed kaltura into Amazon Web Services. But, when I log in as publisher into KMC, and clicking into “Dashboard” and “Analytics” tabs, I get “Internal server error occurred”.
Any help, please?

Hello,

Please run:
# kaltlog
while accessing this tab and paste the output

Thank you jess for your reply,
The output of kaltlog command is:
