After automatic update to 1.9.0.1 can't access Magento Administration Configuration Page. In admin panel where was languages switcher getting this message: "Fatal error: Call to undefined method Zend_Locale::getAlias() in public_html/app/code/core/Mage/Core/Model/Locale.php on line 243"
Can somebody help me with this issue? I had done nothing with FTP or moved any files, just used an automatic update.
