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)
