The wp-login.php script was locked on this server globally due to many bruteforces against it. If you need to login to your wordpress now use this workaround:
Rename wp-login.php to something like wp-login_new.php However simple renaming will redirect you to wp-login.php still, thus some additional step should be done. You would need to replace all
instances of “wp-login.php” in wp-login_new.php file to “wp-login_new.php”. The easiest way to apply this fix would be to run via ssh the following:
cd /path/to/wordpress/
sed -i.backup -e "s/wp-login.php/wp-login_new.php/" ./wp-login.php
cp -Rp ./wp-login.php ./wp-login_new.php
echo "" > ./wp-login.php
