Please can you show which actual URL you were accessing (as seen in the browser URL bar), and also obtain the full backtrace (set EMAIL and ADMINS in configuration.py to get this emailed to you)

However, if this is a bug in Netbox, it's unlikely that it will be fixed in such an old version. If you can't upgrade, you may need to find a local Python programmer who's happy to do it for you.
