Security Ninja and Cron

Unfortunately it appears 1.3.1 did not fix the cron problem. I upgraded and activated 1.3.1 late last night (Au time).

This am I found that cron was failing again. Complete halt.
As soon as I deactivated 1.3.1 cron was ok again.

As I don’t seem to be able to attach a file here I copy all of the txt from php-errors.txt. Hopefully it will help.

Please note that as part of my troubleshooting effort to find out why cron was failing, I deactivated most plugins including Security Ninja and temporarily switched back to Wordfence.

Deactivating Security Ninja did not appear to affect the cron problem believed to be triggered by the Fail2Ban Add-on for Contact Form 7.

If you like, I’ll repeat the process and report further.
