WOrdfence scan error (wfconfig crash @ line 684

Hi,

I have already post an ask for support for this pb.
I have been asked to do a diagnostic and copy the log file but I have no answer for 2 weeks. I understand that it is a free support but I’m stuck with the error.

Each time I do a scan I have a scan failed error.
In the log file, I have the following error “Notice: unserialize(): Error at offset 0 of 1 bytes in /home/ohkzcbw/www/wp-content/plugins/wordfence/lib/wfConfig.php on line 684”

Thanks in advance for your valuable help
