Where can I access server logs in Plesk to investigate a 404 error?

To access server logs in Plesk for troubleshooting a 404 error: 1. Log into your Plesk panel. 2. Go to 'Domains' in the left sidebar. 3. Click on the domain name experiencing the error. 4. Click on the 'Logs' tab. Here, you'll find various logs, including 'Apache error logs' and 'Nginx error logs' (depending on your setup), as well as 'Apache access logs' and 'Nginx access logs'. The error logs will contain messages related to why the resource couldn't be found, while access logs show all requests and their HTTP status codes, helping you identify which URLs are returning 404s.
