Academy ThemeBrowser Info Environment
We did not include the login/logout link on our theme since most users would just type inhttp://yoursite.com/index.php/login... to access the login page.
The code to add back the login/logout link is:
<?php echo Core::make('helper/navigation')->getLogInOutLink()?>
Just add that to the footer, header or anywhere you want.
If you are unfamiliar with adding the code, let us know so we can assist you.
Thanks and regards.
