I have a problem. Today I have to upgrade(manually) wordpress with the latest version. I followed the steps that I found on the wordpress website. But at the end of the ugrade(after the upgrade of the database) appear this string: Fatal error: Call to undefined function is_admin_bar_showing() in /home/pittbocc/public_html/wp-includes/post-template.php on line 505.
The line 505 is this: if ( is_admin_bar_showing() )
$classes = ‘admin-bar’;
What is it? Can you help me? Thank you!!!!!!
