Menu bar is is not visible when using django framework example

[tomschoute]

I am following example: 1. Create an app and add a page template from the django tutorial on the splunk site to create an app.

I've created my app but if I go there there is no top splunk navigation bar (after the splunk> the "app menu - Administrator - Messages - Settings - activity - Help" are all not shown)
Also the Home and app name are not visible in the grey area just below the black top splunk menu (on the page1.html page that I created following the instructions on above mentioned page).
What is causing this? What do I miss?

Only difference I can see so far is that I have a slightly different URL in my splunk: there is a /en-us/ in my URL which is not in the one which is used on the splunk example page.

Can anyone please help me out here? I'm trying to evaluate if a splunk app might be something which is of interest for my customers. But I get stuck on the first step...

[httpServer]

defines the stylesheet relative URL to apply to default Atom feeds;

set to 'none' to not write out xsl-stylesheet directive

atomFeedStylesheet = /static/atom.xsl

max-age = 3600
follow-symlinks = false

reject web accesses over 800MB in length

max_content_length = 838860800

When HTTP client streams data to HTTP server, server will timeout write operation after

streamInWriteTimeout seconds if it cannot make write progress.

streamInWriteTimeout = 5

acceptFrom = *

Automatically tune these limits:

maxThreads = 0
maxSockets = 0

forceHttp10 = auto
crossOriginSharingPolicy =
x_frame_options_sameorigin = true
allowBasicAuth = true
basicAuthRealm = /splunk
allowCookieAuth = true
cookieAuthHttpOnly = true
cookieAuthSecure = true
allowEmbedTokenAuth = true
dedicatedIoThreads = 0

sorry about the format, not sure what went wrong. Just copy/pasted from text file

This looks ok. What about stanza [mimetype-extension-map]? Can you please share the configuration?

Can you please try any solution listed @ http://stackoverflow.com/questions/24528211/refused-to-execute-script-from-because-its-mime-type-app...

I don't really know how to try those solutions.
I did stumble into below section in web.conf:

override MIME type for JSON data

If this is set to True, the splunkweb appserver will serve up JSON data with

a content-type of "text/plain; charset=UTF-8". This keeps it compatible with previous versions of Splunk.

If this is set to False, the content-type will be "application/json; charset=UTF-8" as is standard.

In a future version of Splunk, this default will change so that the standard content-type

is used consistently between splunkweb endpoints and splunkd endpoints accessed through proxy

override_JSON_MIME_type_with_text_plain = True

Which looked like it has something to do with my issue but after creating a web.conf in $SPLUNKHOME\etc\system\local, change the entry to False and restarting splunk I still have the same issue....
