Hi, thanks for fast reply.
In the same time, I found a post related to broken RSS which suggest to disable all plugins to see if the issue come from an incompatible one.
This is what I’ve done so I’ve just found that a required plugin for previous theme (‘ST Kit’ plugin by strictThemes.com) was the origin of the problem.
Everything is OK now, thanks a lot for your support.
I’ve sent you a link to our website but did not have any reply, did you get my email ?
I can guarantee that RSS feed is not working properly because if I just switch back to my previous theme without touching anything else, RSS feed works properly.
Could you please review it carefully ?
