I just upgraded a v.1.3.0.2 site to v.1.3.7 and before running zc_install I got the errors copied below. After running zc_install, the errors are still there. I re-uploaded the admin/includes/languages/english.php and includes/languages/english/email_extras.php files, but the error persists. Any ideas what to check?
