Bug

When trying to set up a massmailing and trying to send a Test mail I fail with an error when using PHP8.2, but all is fine with PHP7.4. I use Password and Swift Mailer socket library (smtp.office365.com)

AH01071: Got error 'PHP message: PHP Fatal error: Uncaught TypeError: preg_split(): Argument #2 ($subject) must be of type string, array given in /htdocs/includes/swiftmailer/lib/classes/Swift/Mime/Headers/AbstractHeader.php:312\nStack trace:\n#0 /htdocs/includes/swiftmailer/lib/classes/Swift/Mime/Headers/AbstractHeader.php(312): preg_split()\n#1 /htdocs/includes/swiftmailer/lib/classes/Swift/Mime/Headers/AbstractHeader.php(259): Swift_Mime_Headers_AbstractHeader->getEncodableWordTokens()\n#2 /htdocs/includes/swiftmailer/lib/classes/Swift/Mime/Headers/UnstructuredHeader.php(103): Swift_Mime_Headers_AbstractHeader->encodeWords()\n#3 /htdocs/includes/swiftmailer/lib/classes/Swift/Mime/SimpleHeaderSet.php(309): Swift_Mime_Headers_UnstructuredHeader->getFieldBody()\n#4 /htdocs/...', referer: https://WWW.XXX/XXX/htdocs/comm/mailing/card.php?action=test&token=c9911ad4d077eabb07f5597a92641508&id=15

Hello,

I cannot reproduce with the latest Dolibarr (19.0.4 from Github), can you test with the latest code please ?

Greetings.

Still same problem and now I'm on 19.0.4. To be sure we talk about the same thing, pls see the below image of where in Dolibarr I am.

Thank you for your quick reply, I reproduced by setting the field "Errors to/Erreurs à" field that was not set in my first test. I'll work on a fix
