Web Framework : Page not Found

Good day

I was working with the Splunk 6 new web framework and I would like to have another html file but when I try to access it an error message has appeared:

Page not found (404)
Request Method:     GET
Request URL:    http://10.103.23.215:9000/dj/en-gb/tw_s6/user_home/

Template 'None:user_home.html' does not exist.

I have checked that my html is on the right folder but why does the Splunk doesn't find it. Tried restarting the instance multiple times. Also used : /debug/refresh but the page still wont load. I'm using Linux server btw.

Thanks
