     18    Debugging help 
     19    ~~~~~~~~~~~~~~ 
     20    If you only see something like 
     21        - "FastCGI Unhandled Exception" 
     22        - "Internal Server Error" 
     23        - "Premature end of script headers" 
     24    try this: 
     25        - Set a LOGFILE 
     26        - use the runfastcgi() options: 
     27            daemonize="false" 
     28            maxrequests=1 
     29        - Use ./tests/server_tests/fastCGI_test.fcgi 
     30        - Try to turn on the flup traceback, see: 
     31            http://code.djangoproject.com/ticket/6610
