Spanish Accents in File Attachment

Please, any help with this?

I try to edit “classes.php” without success ??

What error with what file name exactly?

When I upload a file named with something like ‘testfile – áéí.doc’ (accents in the filename), I get an error that corresponds to the option:
“# Sender’s message was failed to send”

Only happens when the filename contains special chars, what can I do to fix it?

Thanks!

And… I tried to do something like this in classes.php (function mail_attachments):

foreach ( (array) $this->uploaded_files as $name => $path ) {
	if ( false !== strpos( $template, "[${name}]" ) && ! empty( $path ) ){
		$path = str_replace(' ', '-', $path ); // Replaces all spaces with hyphens.
		$path = preg_replace('/[^A-Za-z0-9\-]/', '', $path); // Removes special chars.
		$attachments[] = $path;
	}
}

But when I download the file in the generated mail, it’s empty ??

Maybe it’s specific to your server settings. I just tested to upload and attach “testfile – áéí.doc” on my test environment and didn’t see any issues. Try checking the PHP error logs on your host.

And, don’t edit plugin’s files. It doesn’t solve any issues and can make the situation worse.

Thanks for your reply.

I check my logs but seems it’s everything OK (and is not!):
