I have seen many similar posts describing the problem I am experiencing, but I have been so far entirely unsuccessful in trying to resolve it. I recently upgraded to Magento CE 1.9.1.0, and now I get a blank page when navigating to System > Configuration in the back-end. The rendered page contains only empty html and body tags.
The error:
The only error that I get (in the logs or on screen with display_errors enabled in the index.php) when opening the configuration page (or any other admin page) is the following:
Fatal error: Call to undefined method
Zend_Locale::getAlias()in app/code/core/Mage/Core/Model/Locale.php on line 243
Referer: http://example.com/index.php/magento/index/index/key/.../
The relevant line from Locale.php is:
$allowedAliases[Zend_Locale::getAlias($code)] = $code;
I have attempted:
- Refreshing and/or disabling all caches.
- Disabling all non-Mage modules in
app/etc/local.xml(disable_local_modules),app/etc/modules(<active>false</active>),app/code/localandapp/code/community(removing all files). - Tried both PHP 5.4.16 and 5.5.21
- Comparing all files in
app/andlib/with those from a fresh install. None were missing, but I attempted refreshing them anyway. - Refreshing the user permissions by opening and saving the Administrator role in System > Permissions > Roles.
- Checked and re-checked file permissions, having tried both the Magento recommended perms and fully permissive (777).
System specs:
- CentOS 7
- Magento CE 1.9.1.0
- PHP 5.4.16 or 5.5.21

The only error that is evident in the logs is the persistent Locale.php one. – Craig Stone Mar 12 '15 at 10:34display_errorsenabled in the index.php, the configuration page displays the same error that I'm seeing in the logs:Fatal error: Call to undefined method Zend_Locale::getAlias() in .../app/code/core/Mage/Core/Model/Locale.php on line 243.
