I follow this instruction
\ow_system_plugins\base\init.php
Remove the highlight part in bold and try.
$router->addRoute(new OW_Route('base_user_profile', 'user/:username', 'BASE_CTRL_ComponentPanel', 'profile'));
Working well but not work on notification: it is still site.com/user/name
I tried search on ow_plugins/notifications/ but not found...
Thank You
