 * Hi,
 * I fixed the other problem but now getting this:
 * `[Sep 08 00:06:40] Scan Engine Error: Wordfence could not start a scan because
   the cron key does not match the saved key. Saved: b979b5eb61fb154ae08dbb Sent:
   218ee8e56737a81244f7478c Current unexploded: 1410131175,b979b5eb61fb154ae08dbb`

 * Hi
 * Thanks for using Wordfence but sorry you are having issues. Can you go to the
   options page, scroll to the bottom and look for a check box that says disable
   config caching? Check the box and hit save, then run a scan. You shouldn’t have
   that error anymore.
 * Let me know if you do or don’t so I can resolve the case. Thanks!

 * Hi Tim,
 * No thank you for such a great plugin. I have done what you suggested and all 
   seems good now. There was already a scan in progress but from the code below 
   all seems good.

 * I was actually so impressed with your plugin after trying another that caused
   major problems I done you a mini review and link back [here](http://anti-cap.com/wordfence-security/).
