I made a post on the open edx google groups regarding this issue, pasting the same below. It includes the traceback captured from the edxapp logs
We've just set Bitnami's image of Open EdX on our AWS server. The issue is that Problem Components don't render in LMS, they render correctly in Studio though. I found that an exception is being thrown the from endpoint 'invokexblock_handler' in the file "/opt/bitnami/apps/edx/edx-platform/lms/djangoapps/courseware/module_render.py". The library 'newrelic.agent' is being imported in the start of this file, but looks like the import actually fails.

I've done a pip install of newrelic just to be sure and looks like the lib is already available in the env :
bitnami@ip-172-31-11-2:/opt/bitnami$ sudo ./use_edx
root@ip-172-31-11-2:/opt/bitnami# source /opt/bitnami/apps/edx/edx-platform/venv/bin/activate
(venv)root@ip-172-31-11-2:/opt/bitnami# pip install newrelic

Requirement already satisfied (use --upgrade to upgrade): newrelic in ./apps/edx/edx-platform/venv/lib/python2.7/site-packages/newrelic-126.96.36.199
You are using pip version 7.1.2, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
can anyone help with any insights into this?
Hope this helps expedite a fix for this.
Our open edX instance is unusable because of this issue, any workarounds till this gets fixed?
