hah! thanks markus, just banged against this one, this was definitely the fix (btw still present in v6.3)
thanks for saving me the frustration of trying to figure this one out :)
I am happy the post was of some value to someone even if it was an old one.
Thanks Markus. Just ran into this exact problem with a 7.0 site.
This post probably saved me hours of time and a headache :-)
Glad the post was to some use for you. However how easy would it be for Telerik to add under Admin - Modules - Search and Indexes a small note (Needs Feeds & Notifications to be turned on)
So it would at least give a user a chance to know what to do :-). But thats me and my usability thinking.
