I have more than one Treasury tab in my menu.

[Resourcez]

Cause:
Due to an incorrect uninstall operation, invariably due to uninstalling out of sequence and re-installing, and usually accompanied by warnings in the Package Manager that there were problems.
Cure:

• open up Themes/default/index.template.php
  
  
• remove the duplicate Treasury button section(s)

Code: [Select]

// the [treasury] button
if ($context['allow_view_treasury'])
echo ($current_action == 'treasury' || $context['browser']['is_ie4']) ? '<td class="maintab_active_' . $first . '">&nbsp;</td>' : '' , '
<td valign="top" class="maintab_', $current_action == 'treasury' ? 'active_back' : 'back', '">
<a href="', $scripturl, '?action=treasury">', $txt['treasury_menu'], '</a>
</td>', $current_action == 'treasury' ? '<td class="maintab_active_' . $last . '">&nbsp;</td>' : '';

• If you do not understand that , use the Package Parser
  Click the "uninstall" option to show you what needs to removed and from where.

Note:
This issue usually means other sections of Treasury have been duplicated.
Use the Package Parser to find where these might be, and adjust the relevant file.
