Try to install the latest version of the facebook plugin. I think the email issue is fixed.

I am running a NodeBB for a small local community

site: http://iduo.ca

current working on a lots of integrations into it by leveraging its read and write APIs. Just wanna say, I like NodeBB and wish more features could come out sooner!

I did not see any errors in the log. I ended re-config my whole nodebb from fresh and now the sitemap generation works. Don't know why.
