Already fixed in master

This error is also shown to me when I send an email.

Like the thread already says, this has been fixed. Update your PHPMailer.

[silviodelgado]

My version is the last stable (6.0.7) and the problem are still there.

[Synchro]

The FILTER_FLAG_SCHEME_REQUIRED constant is not used anywhere in the current release. Double-check your versions.

Sorry for my complain.
My VSCode cache from Github was keeping the old code, instead of update it (even after composer.json update)

Sorry for my complain.

in my composer.json is

"phpmailer/phpmailer": "v6.1.7",

how did you force composer to use the new version?

well, and we use php 7.4

[Synchro]

Change your composer.json to:

"phpmailer/phpmailer": "^6.1",

Then update (just PHPMailer) using composer update phpmailer/phpmailer. This pattern will match semver numbering and will get the latest version of PHPMailer 6.x.x, currently 6.1.8.
