maninfjugesta on "[Plugin: Wordfence Security] "Scan can't continue ... " - not hapyy with "disable malware scan""

On May 9th Wordfence scans began to fail to complete: "Scan can't continue - stored data not found after a fork. Got type: boolean". I disabled the malware scan and the scan completed - which is clearly a self-defeating solution. Any suggestions?

I'm running wp 4.5.2 and Wordfence 6.1.7. (I update Wordfence within 24 hours, max 48, of a new release. I can't remember whether or not it was 6.1.6 or 6.1.7 on the 9th of May.) W3 Total cache is active

I look after a number of sites on the same server and no other site has the problem.

By the way, I can't find the "disable config cache" option that you mention in previous posts. Have you removed this possibility?
