Wordfence Security Plugin Issues 18-01-2017

Two of my WordPress websites were down and I was unable to access /wp-admin therefore I requested help from my webhost to resolve the problem.

They informed me that the Wordfence plugin was the cause of the problem and they deactivated the plugin in order to restore the website(s) as can be seem in the following…. so as I have been happy using Wordfence up to now, how do I resolve this problem?
