Wunderadmin Magento Admin Theme overrides two page templates: header.phtml and footer.phtml. If some other extension, like Localized one overrides them too it will cause issues with admin theme.
To solve this problem need to override them again. To do it copy header.phtml and footer.phtml templates from /app/design/adminhtml/default/default/template/magento_localized/ to /app/design/adminhtml/default/wunderadmin/template/magento_localized/ and do the following changes to them:
/app/design/adminhtml/default/wunderadmin/template/magento_localized/header.phtml
Replace logo image src on line 15.
<div class="header-top">
<a href="<?php echo $this->getHomeLink() ?>"><img src="<?php echo $this->getSkinUrl('images/logo.gif') ?>" alt="<?php echo $this->__('Magento Logo') ?>" class="logo"/></a>
<?php echo $this->getChildHtml('logo') ?>
<div class="header-top">
<a href="<?php echo $this->getHomeLink() ?>"><img src="<?php echo Mage::helper('wunderadmin')->getWunderLogo() ?>" alt="<?php echo $this->__('Magento Logo') ?>" class="logo"/></a>
<?php echo $this->getChildHtml('logo') ?>
/app/design/adminhtml/default/wunderadmin/template/magento_localized/footer.phtml
Copy javascript code with waButtons, waTheme and jscolor.dir definition from Wunderadmin Magento Admin Theme original footer.phtml template located at /app/design/adminhtml/default/wunderadmin/template/page/ to javascript part of new footer.phtml template.
