I'm trying to update my current installation to the latest version, but after the update, pages are blank, and I’m seeing several error messages in the logs. Specifically, I'm getting warnings about "Undefined array keys" and fatal errors like "Table 'itflow.custom_links' doesn't exist." Has anyone else encountered these issues during an update, or does anyone know a fix?
