Bad Behavior WordPress plugin v.2.2.11 has a typo (missing a comma) in file blacklist.inc.php on line 94. To resolve this issue, go to (via SFTP)
/wp-content/plugins/bad-behavior/bad-behavior
and edit blacklist.inc.php on line 94 by adding a comma after “Nikto/”
so it looks like “Nikto/”,
That should allow you to regain full control of your dashboard once again.
