You can change this in phpbb_seo/phpbb_seo_class.php if you prefer.
Look for :

'index' => ''

In this line of code :

$this->seo_static = array( 'forum' => 'forum', 'topic' => 'topic', 'post' => 'post', 'user' => 'member', 'group' => 'group', 'index' => '', 'global_announce' => 'announces', 'leaders' => 'the-team', 'atopic' => 'active-topics', 'utopic' => 'unanswered', 'npost' => 'newposts', 'pagination' => 'page', 'gz_ext' => '.gz' );

And replace with :

'index' => 'forum'

or whatever you may prefer.
This is mostly useful if you're running a portal in the folder where phpBB is installed.

You can change this in phpbb_seo/includes/setup_phpbb_seo.php if you prefer.
To do this, you can for example add :

$this->seo_static['index'] = 'forum';

before :

// Let's make sure that settings are consistent
$this->check_config();


This is mostly useful if you're running a portal in the folder where phpBB is installed.

=> The first setting to do is to select which static part to use in your URLs.

To do so, you can override default values in phpbb_seo/includes/setup_phpbb_seo.php, still before :

// Let's make sure that settings are consistent
$this->check_config();
