I have two sites running 3.9.1
On one site Wordfence reports no errors.
On the other it reports two errors:
1- WordPress core file modified: wp-includes/version.php
and
2- WordPress core file modified: wp-config-sample.php
the changes are minor:
in 1 in line 38: $wp_local_package = 'en_GB';
in 2 in line 72: define('WPLANG', 'en_GB');
I repaired them both but now WP report that there is an update available.
What to do?
