   storage/file.php line 318 (pulse) Can you fix it or let me know what I need to
   do?

 * Hi,
 * Thanks for getting back to us.
 * I have tried it in learning mode and still seem to get the same errors.
 * Only disabling the firewall seems to fix the issue.
 * Thanks

 * I switched my firewall status to “Learning Mode” and clicked save. I got confirmation
   that it saved. Immediately my error log started filling up with the same error
   message, and my cron jobs stopped executing.
 * I then went to the “Live Traffic” tab and switched to “Blocked by Firewall” –
   it showed nothing, again.
 * I turned the firewall back off, and it resumed working.
