Error: wp-login-timeout-settings.php on line 261

Getting this error:

[10-Dec-2014 14:53:39 UTC] PHP Warning: in_array() expects parameter 2 to be array, null given in D:\path\to\wp\wp-content\plugins\wp-login-timeout-settings\wp-login-timeout-settings.php on line 261

Not sure when at this point but saw it repeatedly a lot in my error log.
