Q:

Mayan EDMS not working on browser but Nginx and Supervisor is up and running

I just installed Mayan-EDMS on my Ubuntu 16.06 LTS, the services of Nginx and Supervisor are up and running but I can't see it working on the browser, can someone help me out on this?
Please see error log below.

IOError: [Errno 13] Permission denied: 
'/tmp/bbe634d59fe221a7c66f1575eb5214c1c49a3e40ff10d6c8149c25cc217a7d0d'

A:

The error:
IOError: [Errno 13] Permission denied: 

Probably means you installed Mayan EDMS using one user and are running it using another user account. 
The file in the /tmp folder is probably the lock file. 
To fix the issue, stop Mayan and delete the/tmp/bbe634d59fe221a7c66f1575eb5214c1c49a3e40ff10d6c8149c25cc217a7d0d file. It will be created again by the user running the Mayan server subsequently.
