netcentsii on "[Plugin: Wordfence Security] EMERGENCY: Is this a WordFence issue? Is Wordfence blocking access to my websit"

I have not been able to access my Wordpress website that is protected by Word Fence for almost a week.

http://www.netcentsii.com

All I get and my webhoster gets when I go to this site is a blank screen.
The hosting company tried adjusting PHP versions and then turned "display errors" that show these error messages which mention WORDFENCE:

Warning: require_once(lib/wordfenceClass.php): failed to open stream: No such file or directory in /home/wtradio/public_html/sandbox/wp-content/plugins/wordfence/wordfence.php on line 24

Fatal error: require_once(): Failed opening required 'lib/wordfenceClass.php' (include_path='.:/opt/alt/php54/usr/share/pear:/opt/alt/php54/usr/share/php') in /home/wtradio/public_html/sandbox/wp-content/plugins/wordfence/wordfence.php on line 24

Was there a WF update a week or so ago?

I can't access my site at all except through CPANEL of the top level domain.

Do these errors messages point to a WordFence issue? What corrective actions can I take?
Jim
