If you are using PrestaShop you may have come across the bug where if a customer enters their name or address in CAPITAL letters e.g. ME@DOMAIN.com it causes the e-mails to display incorrectly. Instead of their first and last names being displayed, it shows HELLO {FIRSTNAME} {LASTNAME}, THANKS TO CREATE A COSTUMER ACCOUNT {SHOP_NAME}.

The good news this is an easy problem to fix and requires only a one line of coding to be changed

Step 1 : Open PrestaShop's classes/Mail.php file

Open your hosting account and open the file classes/Mail.php. Usually this can be done via a hosting control panels file manager. To edit the file in cPanel's file manager, right click on the file and click edit.

Step 2 : Locate line 556

Scroll down to line 556 and find

$swift->registerPlugin(new \Swift_Plugins_DecoratorPlugin(array($toPlugin => $templateVars)));

Now delete this line (or add a // in front of it to comment it our) and add the new line below instead:

$swift->registerPlugin(new \Swift_Plugins_DecoratorPlugin(array(self::toPunycode($toPlugin) => $templateVars)));

Thats it! Do a quick test by creating a new account on your site and you should see the e-mails come through correctly.
