Github Issue: 1998
I fixed the problem with a plugin:
<type name='\Magento\Store\Model\Store'>
<plugin
name='Df\Store\Model\StorePlugin'
type='Df\Store\Model\StorePlugin'
sortOrder='100'
/>
</type>
<?php
namespace Df\Store\Model;
use Magento\Store\Model\Store;
class StorePlugin {
/**
* 2015-10-01
* «Admin» store title is untranslatable on admin attribute edit page
* neither by a dictionary nor manually.
* @link https://mage2.pro/t/99
* @see AbstractFrontend::getName()
* @param Store $subject
* @param string $result
* @return string
*/
public function afterGetName(Store $subject, $result) {
return 'Admin' === $result ? __($result) : $result;
}
}
