after upgrading from 3 to 4 i now cannot send emails. i get 2 sets of errors.
1. Warning: Could not instantiate mail function.
2. Error 500.
using casseopeia

using my template

i use smtp to send emails however i get the same results if changed to php.
when sending a test email through the config. works fine. contact form also works but its using Page Builder Pro. that works. basically cannot successfully send an email to a contact set up through the Contact Component.

Does anyone know how i can fix this or point me in the right direction to a fix?
cheers, stella.
