Hi,
I try to activate phpmailer + email-newuser extensions and I have this error when creating a new user:
EXCEPTION (0) : Call to undefined function bool() in/server_fullpath/zp-core/zp-extensions/PHPMailer.php à la ligne 123

I have not activated sendmail as I wish to use phpmailer to connect to external smtp using TLS 587 port. All phpmailer settngs are OK.
My version is
Version Zenphoto 1.5.7b-DEBUG
PHP Version 7.3.14-1~deb10u1

Any idea to investigate?

Thanks

Thanks. That was a typo. Fixed in the Support build.

Great, thanks for fixing!
