I have this problem aswell. And I have tried to do it manually. Searching for the code and adding it myself. I can't find any similar place to ad it in, as refered in the installation file. And I just can't paste the code randomly and hope for the best.
Code searched in Admin.php
'current_theme' => array(
'label' => $txt['theme_current_settings'],
Code searched in Subs.php
'mlist' => array(
'title' => $txt['members_title'],
'href' => $scripturl . '?action=mlist',
'show' => $context['allow_memberlist'],
'sub_buttons' => array(
'mlist_view' => array(
'title' => $txt['mlist_menu_view'],
'href' => $scripturl . '?action=mlist',
'show' => true,
),
'mlist_search' => array(
'title' => $txt['mlist_search'],
'href' => $scripturl . '?action=mlist;sa=search',
'show' => true,
),
),
),
While theres is more code that are searched for in Subs.php I choosed to paste the the one that I had problem with.
If I for instance would only search for a part of the code "'title' => $txt['mlist_search']," it won't find it either. And the code for Admin.php is the same, not there.
If the OP is still around how was the problem solved, or do anyone else have any solution to this.
