My error log is filled with lines like this:
Content visible to verified customers only.
At times this brings down my server.
The file cron.php, the folders clientscript & images do not exist at that location.
Mind that the IP address does not seem to match any member account, so its most likely a guest. Search options > Require users to be registered to use search? is set to NO.
Do you have any idea what is causing this?
