404 Not Found Error in logs

Hello, i see a error log in the php logs
I dont know why and thats mean


You may compare with your Apache logs to find out.

Apache error logs doesnt show a related error to this

Did you grep for " 404 " in the corresponding Apache access log? (not the error log)

404 HTTP status error may come from

  • bots trying to find PHP / Wordpress vulnerabilities
  • bots using faulty URLs
  • Access to non-existing .map files from the JavaScript libraries used by OJS (Poppler, Bootstrap, and others depending on plugin used)
