I recently had a site called fight4cash.co.uk. This was my test website before I bought my new domain and went live with my new website.
My host has copied everything to my now live site. treatmeathome.com
However whenever someone makes a booking in appointments+ the confirmation and reminder emails are not being sent from my default wordpress email admin. They're coming from my old admin email (firstname.lastname@example.org)
my host believes everything is ok at his end.
Interestingly the order email is coming from my default wordpress email. I should also point out I've tried deleting the appointments plug in and reinstalling it (which took a while) only for it still not to work
