How to change the SMF index page title?
To change your SMF application’s index page title, edit the following file:
~/SMF_installation_directory/Themes/default/languages/index.LANGUAGE.php
where LANGUAGE is the current language which your application is using.
You will have to find the following line:
$txt[18] = $context[‘forum_name‘] . ‘ – Index’;
and change the value of the forum_name variable to the desired title.
Note that you can modify this file via FTP, or using File Manager in Site Tools.
After the change, your new title should appear on your SMF home page.
