Question Approved by administrator - Problem

I should activate a new user, but I get this error message:

Fatal error: Declaration of Egulias\EmailValidator\Validation\MessageIDValidation::isValid(string $email, Egulias\EmailValidator\EmailLexer $emailLexer): bool must be compatible with Egulias\EmailValidator\Validation\EmailValidation::isValid($email, Egulias\EmailValidator\EmailLexer $emailLexer) in /var/xxxxxxx/vendor/egulias/email-validator/src/Validation/MessageIDValidation.php on line 23

See www.webtrees.net/index.php/en/forum/help...ter-update-to-2-0-21
tl/dr: delete the file /vendor/egulias/email-validator/src/Validation/MessageIDValidation.php

> delete the file /vendor/egulias/email-validator/src/Validation/MessageIDValidation.php

...or upgrade to 2.0.22

Thanks for the help.
