 * Got this error this morning while a scan was running – any ideas?
 * Scan Engine Error: Wordfence could not start a scan because the cron key does
   not match the saved key. Saved: 7445103660390113ac4ce5e Sent: 418ec8fed2ef74a83a57

 * Hello endlessimagery,
    there are two things you can try.
 * 1. Disable config caching. This option is available on the Wordfence “Diagnostics”
   page at the very bottom.
 * 2. Go to Wordfence “Options” page and under “Other Options” change the setting“
   Maximum execution time for each scan stage” to 15.
 * Let me know if either of those work.

 * thank you! the first option worked just fine – seemed to take a little longer
   to complete but it worked. Any idea why this would happen? Thanks again!
