You have to add
'xoops_name' => $GLOBALS['xoopsUser']->getVar('name'),
in /class/theme.php after
'xoops_uname' => $GLOBALS['xoopsUser']->getVar('uname')
,
In older versions 2.3.x-, it is
'xoops_name' => $xoopsUser->getVar('name'),
=>
'xoops_uname' => $xoopsUser->getVar('uname'),
Maybe also to modify is /include/xoops13_header.php
Should maybe useful enough to add in the core.
