obviously had been a missing file problem, too. Now it works.
Hi Samuel Wood,
many thanks for your reply. I had deleted all the files and replaced with fresh ones from WP 4.0 using Filezilla as FTP tool. I will try this with WP_DEBUG and report asap.
Hi Samuel,
since I still have nearly the same problem, I like to know what has been the problem with the manual upgrade? She deleted /wp-admin and /wp-include and reloaded the new files via FTP! What has been wrong? Could you give me more details please.
Many thanks & best regards
EDIT: Could solve the problem by changing the 2nd line
<?php
$value = get_bloginfo( 'language' );
if ($value == "de-DE") {
wp_nav_menu( array('menu' => 'Footer Menu' ));
}
else wp_nav_menu( array('menu' => 'Footer Menu E' ));
?>
