Cannot access Module Admin in FreePBX 12.0.76.3

Hello,

I have problem accessing Module Admin in FreePBX 12.0.76.3. I go to Admin->Module Admin, but it doesn’t load module admin page. I want to upgrade some modules that are available. Please check bellow log in /var/log/asterisk/freepbx.log. Please help to check and let me know what to do next.
Thanks.
