Vicky’s server guides

In case your Python is giving your problems on EnsimX server and you get  “500 Internal error” errors then thig guide can help you. I found it on ensim forums and it helped me so I saved it for future reference.

Here is the error message:

500 Internal error
Internal Server Error

——————————————————————————–
Hints :-
Check logs files in /var/log/ensim/ for debug information
Ensure URL typed is correct

And here is what will be in your log :

TypeError: generate_content() takes exactly 1 argument (2 given)

And the fix is to recompile templates, restart Ensim and reboot server:

cd /usr/lib/ensim/frontend/kidpages/
/usr/bin/kidc -f *
service epld restart
reboot
