error codes

I´m working in localhost.
When I activate the plugin, it shows me these two errors:

\wp-content\plugins\wp-hide-security-enhancer\include\wph.class.php on line 658

\wp-content\plugins\wp-hide-security-enhancer\include\wph.class.php on line 665

Looking at google, I see that there are several sites that have this error too. For example: http://www.euformed.it/2017/09/06/

How do I solve it? Will it have to do with the WordPress last update?

Thank you!
