When I try to test the contact us form, I get an error:
Sorry, don’t know what happened. Try later!
I can’t find any documentation on this topic – is there something I have to setup in the Theme or in WP itself?
Indeed: sh: 1: /usr/sbin/sendmail: not found
Do you have a package that includes sendmail with default configs or do I have to install and configure it on my own?
