go to file : lib -> weblib.php

then find a function named: user_login_string

then go to its end at the line that begins with the word "return"

delete this line and put this line instead:

return "(<a $CFG->frametarget href=\"$CFG->wwwroot/login/logout.php?sesskey=".sesskey()."\">".get_string('logout').'</a>)";

then SAVE.
