It's pretty simple, in phpbb_seo/phpbb_seo_class.php, replace :
| Code: | | $this->seo_static = array( 'forum' => 'forum', 'topic' => 'topic', 'post' => 'post', 'user' => 'member', 'group' => 'group', 'index' => '', 'global_announce' => 'announces', 'leaders' => 'the-team', 'usermsg' => 'messages', 'pagination' => 'page', 'gz_ext' => '.gz' ); |
With :
| Code: | | $this->seo_static = array( 'forum' => 'forum', 'topic' => 'topic', 'post' => 'post', 'user' => 'member', 'group' => 'group', 'index' => 'index', 'global_announce' => 'announces', 'leaders' => 'the-team', 'usermsg' => 'messages', 'pagination' => 'page', 'gz_ext' => '.gz' ); |
and :
| Code: | | $this->seo_ext = array( 'forum' => '.html', 'topic' => '.html', 'post' => '.html', 'user' => '.html', 'usermsg' => '.html', 'group' => '.html', 'index' => '', 'global_announce' => '/', 'leaders' => '.html', 'pagination' => '.html', 'gz_ext' => ''); |
with :
| Code: | | $this->seo_ext = array( 'forum' => '.html', 'topic' => '.html', 'post' => '.html', 'user' => '.html', 'usermsg' => '.html', 'group' => '.html', 'index' => '.php', 'global_announce' => '/', 'leaders' => '.html', 'pagination' => '.html', 'gz_ext' => ''); |
The zero duplicate will follow the setting, it will force the use of index.php, and all the forum link to index will use it
