I know that this issue has been posted many times, but for me it seems to be a different problem.
Indeed, this error
Warning: require(vendor/autoload.php): failed to open stream: No such file or directory in C:\xampp\htdocs\site_web\send_mail.php on line 3
Fatal error: require(): Failed opening required ‘vendor/autoload.php’ (include_path=”C:\xampp\php\PEAR”) in C:\xampp\htdocs\site_web\send_mail.php on line 3
appears at the begining of my code from this line:
require 'vendor/autoload.php';
So, I guess there must be a /vendor/autoload.php file somewhere in my computer (I have installed composer and ran composer require phpmailer/phpmailer).
So, I looked for this file using: dir /s autoload.php in the Windows command line, and found one here: C:\Windows\SysWOW64\vendor\autoload.php,
but for me, syswow64 folder has nothing to see with autoload.php, I don’t see what I am missing here.
