[8.0.3] Error 500 while testing email

[Arnaud Roch-Trève]

Hello,

I am on a fresh install of Prestashop 8.0.3.

While testing my shop, I realized that I didn't receive usual transactionnal emails when buying stuff.

I went to advanced setting > email and tried to send a test email. I got a 500 server error in the ajax call.

Here what I have in the log : 

[2023-05-11 13:42:59] request.CRITICAL: Uncaught PHP Exception Symfony\Component\ErrorHandler\Error\ClassNotFoundError: "Attempted to load interface "Swift_Events_Event" from the global namespace. Did you forget a "use" statement?" at /srv/data/web/vhosts/mytestdomain.com/htdocs/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Events/EventObject.php line 16 {"exception":"[object] (Symfony\\Component\\ErrorHandler\\Error\\ClassNotFoundError(code: 0): Attempted to load interface \"Swift_Events_Event\" from the global namespace.\nDid you forget a \"use\" statement? at /srv/data/web/vhosts/mytestdomain.com/htdocs/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Events/EventObject.php:16)"} []

It is a fresh install, I only installed 1 module for advanced fees.

I tried using SMTP too.

Should I install another emailing module ?

Anyone have a solution ?

Thank you

Hello,

Since I still can't send mail because of configuration it seems, the initial error was because of a corrupted file. He was there but empty.

To upload it again fixed the issue.
