I can see this error in my error log, but it is not exactly easy for me to troubleshoot. I have looked back and have been receiving this error for the past few months. I have no record of making a change to the websites code the day the error started appearing. Notes about my website is hosted by BlueHost - Cloud Hosting, the website uses the WordPress CMS.
Example from my error_log file:
...
[01-Mar-2017 17:02:33 UTC] script not found:<script> </script>
[01-Mar-2017 18:13:24 UTC] script not found:<script> </script>
[01-Mar-2017 20:58:27 UTC] script not found:<script> </script>
Anyone have any idea what may be causing this to appear in my error_log?
