I have had wordfence installed for longer and it always worked fine. today it hangs on:
[Feb 01 15:23:42]Scanning file contents for infections and vulnerabilities
[Feb 01 15:23:42]Scanning files for URLs in Google's Safe Browsing List
saying
[Feb 01 15:24:02] Scan process ended after forking.
I have no idea as to why. Any ideas?
