Illegal string offset warning when trying to send an email from Admin

[dgent]

PHP 5.44, ZC1.38 completely patched up past 1.39 to work with PHP 5.44.

The error above was actually from when I was resending archived emails.

If I send a normal message from the admin side to a user, this is the error messages

Warning: Illegal string offset 'file' in includes/functions/functions_email.php on line 255

Warning: Illegal string offset 'file' in includes/functions/functions_email.php on line 255

Warning: Illegal string offset 'file' in includes/functions/functions_email.php on line 255

Warning: Cannot modify header information - headers already sent by (output started at includes/functions/functions_email.php:255) in admin/includes/functions/general.php on line 26

Fixed the 'file' error messages, inserted new code from Zencart 1.6 files into my includes/functions/functions_email.php and all working perfectly with no errors.

Stilll have the Warning: Illegal string offset 'EMAIL_TO_NAME' in includes/functions/functions_email.php on line 83 from Email Archive Manager, though this is a third party extension.

Did you manage to get this resolved?

I am getting the error

Illegal string offset 'EMAIL_TO_NAME' in

when sending mail using the Autoresponder plugin.
