AcyMailing install Xampp + Localhost error sending email

nunos

Hi everyone,
Just installed Xampp on my local machine (wordpress 5.9 + Acymailing 6.0) for testing purposes, on Ubuntu 22.04
Everything is running smoothly, a can send email trough wordpress contact forms using an external smtp server with proper authentication but when i try to test sending with AcyMailing i get an error:
"There has been a critical error on this website. Please check your site admin email inbox for instructions."
Any ideias what could be the problem?
Thanks!

Did you check the server error logs to see the real PHP error message that could be written there?

That's what i have on the logs when i try to send a test email:

Maybe that'sthe problem...

[30-Nov-2022 16:09:12 UTC] PHP Fatal error: Uncaught Error: Undefined constant "acyPHPMailer\FILTER_FLAG_HOST_REQUIRED" in /opt/lampp/htdocs/newsletters/wp-content/plugins/acymailing/front/inc/phpmailer/phpmailer.php:3609

That'swhat i have a line 3609 of phpmailer:

if (filter_var('http://' . $host, FILTER_VALIDATE_URL, FILTER_FLAG_HOST_REQUIRED)) {
//Is it a syntactically valid hostname?
return true;
}

Hum... i have found this info:

The FILTER_FLAG_HOST_REQUIRED filter flag was deprecated in PHP 7.3 and there are no longer any references to it in the PHPMailer code base.

Running php 8 : (

Ok, so for anyone running in to the same problem i think i have found a fix.
Just remove the deprecated variable from the phpmailer.php file (FILTER_FLAG_HOST_REQUIRED).
Just tested it, it working!
Hope it will not mess anything else 🙂

This is happening because you are probably running this site as localhost

If you define a domain in your hosts file that points to 127.0.0.1 and use that domain instead of localhost, you shouldn't have to remove this variable and everything would work as expected

OK thanks, going to try to change localhost

Another change needed for user subscription and import:
/wp-content/plugins/acymailing/back/classes/user.php
WHERE user_id IN ('.implode($usersId, ",").')
Change ' to []
