list index out of range error

[corpulent]

Hey guys, I keep getting this error. I can interact with elasticsearch through python shell without a problem, and update indexes. I can also connect to elasticsearch service through http. I think somehow aldryn_search is involved, which is why I created this issue here.

Here is my settings.py just in case http://pastebin.com/BbxDen35

@corpulent are you using django < 1.5 ? The problem is that to bypass django's exception on host headers, we have to pick a host from ALLOWED_HOSTS setting which in your case is empty, causing the IndexError. If you are using django < 1.5 then you can add localhost to ALLOWED_HOSTS

@czpython I am using django 1.6.5 , my pip freeze http://pastebin.com/XtHV6ShG. I added localhost to ALLOWED_HOSTS, and now getting this error. NoReverseMatch: u'aldryn_blog' is not a registered namespace

@corpulent ok then please make sure you change the ALLOWED_HOSTS to something correct domain when in production.

Regarding your error, please make sure you have added the aldryn blog apphook to a page.

@czpython thank you very much! I should have tried that, so obvious...
