Wondering if anyone can where to find and fix this error when I tried to upgrade:

Error: Message could not be sent. Mailer Error: Could not instantiate mail function.

It keeps me from upgrading from 4.11.2

Any reason why you haven't set it up?

do not know the setup. I am not on a regular hosting. Can you show me how and what...? Thanks

So your store hasn't been sending any emails at all?

You will need to have it set up on your server and then copy the required credentials into the settings. It will probably require the assistance of your server administrator.

The Tool: No I have not been sending mails from site as the site is in development and moving fast to launch. Also , I have one of those UN-managed VPN type server and there a guy that helped me set it up but said the server does not have a mail client/server capability and that it looks like i will have to get something like a G-Suite to send order emails.

eComLabs: Thanks for the link. Will take a look and see if any of it will help me.

BTW, is it customary for the site to want to or send email out after an upgrade? If so, where is the mail been sent to?

During upgrade the system send restore link to the administrator email. If something went wrong, admin will be able to revert back the upgrade

You can always enable development mode and skip backup during upgrade
