I tried to live edit base.py template but now my app has internal error. I undo the changes but still get 500 error while accessing website. Tail -f of my application_name.log shows:

File "/home/jalala/projects/Hamkharid/eggs/Django-1.3.1-py2.7.egg/django/template/base.py", line 108, in __init__
self.nodelist = compile_string(template_string, origin)
File "/home/jalala/projects/Hamkharid/eggs/Django-1.3.1-py2.7.egg/django/template/base.py", line 136, in compile_string
return parser.parse()
File "/home/jalala/projects/Hamkharid/eggs/Django-1.3.1-py2.7.egg/django/template/base.py", line 237, in parse
self.invalid_block_tag(token, command, parse_until)
File "/home/jalala/projects/Hamkharid/eggs/Django-1.3.1-py2.7.egg/django/template/base.py", line 291, in invalid_block_tag
raise self.error(token, "Invalid block tag: '%s'" % command)
TemplateSyntaxError: Invalid block tag: '%20get_static_prefix%20'

And tail -f of error.log shows:

It looks like your changes weren't undone correctly, given the "Invalid block tag" error. I would double check that tag, make sure it is correct, and make sure than any required loading is done for that tag to be available to the template.

The other error (TemplateDoesNotExist) is really related to the first error: the first error would show a "500" page to the user, but since you don't have a 500.html template defined, you get the "TemplateDoesNotExist" instead.

Also, your "undo" may not have been picked up by the app; I would also try restarting your webserver.

It looks to me like you do not have 500.html file in your base
template directory. If you have a server error in production mode
(DEBUG = False), django will show 500.html to users. So users will not
see actual error message. But you will get that message by email.
Since you do not have 500.html it gives you template does not exist
error instead of actual error message. This will not help you to solve
your problem, but at least it will help you identify it.
