Remove annoying [Shop Name] prefix on email subject, version 1.7

[Mercader Virtual]

Hi,

I know this question has been asked several times. I tried different solutions but something weird is going on:
 

I edited Mail.php and managed to strip out the shop name $subject.

// Hard-coded replacement, just in case.
$subject = str_replace("[".Configuration::get('PS_SHOP_NAME')."] ", "", $subject);
$message->setSubject($subject);

I checked the $message object just before swift execution:

$send = $swift->send($message);

The subject appears to be correct (without the shop name),  as expected. But guess what?

Still some emails are arriving with that freaking "[Shop Name]" prefix! Funny enough, not all, that is, some are arriving without the shop name.

I thought it was something related to smarty cache, so I clear the cache. It didn't work

Any other ideas? Thanks.

Clear cache and testing for new order , then it's work for me, but for old order it's still this prefix with [PS_SHOP_NAME]

You should replace in line ~460 (file /classes/Mail.php, function send()):

/* Create mail and attach differents parts */
$subject = '[' . Configuration::get('PS_SHOP_NAME', null, null, $idShop) . '] ' . $subject;
$message->setSubject($subject);

to:

/* Create mail and attach differents parts */
$message->setSubject($subject);

Then it should work.

It works great.

I found out that it can be more simple. At least for V8.1 and above... Go to your database and select the configuration:

SELECT * FROM ps_configuration WHERE `name` = 'PS_MAIL_SUBJECT_PREFIX';

You will see a value of 1. Change this to 0 and apply changes. Now your title won't show your website inside the brackets.
