• Please be aware: Kaspersky Anti-Virus has been deprecated
    With the upgrade to Plesk Obsidian 18.0.64, "Kaspersky Anti-Virus for Servers" will be automatically removed from the servers it is installed on. We recommend that you migrate to Sophos Anti-Virus for Servers.
  • The Horde webmail has been deprecated. Its complete removal is scheduled for April 2025. For details and recommended actions, see the Feature and Deprecation Plan.
  • We’re working on enhancing the Monitoring feature in Plesk, and we could really use your expertise! If you’re open to sharing your experiences with server and website monitoring or providing feedback, we’d love to have a one-hour online meeting with you.

Question Plesk is not logging 500 errors?

Thanks for the answer. I can see entries in access logs, but nothing in error logs. Shouldn't be there some explanations about it in the error log?
 
It is only logged in access_ssl_log.
How can I find out what's the reason behind this 500 error?

Example:

40.77.167.53 - - [16/Dec/2022:07:00:14 +0100] "GET /free-pdf-manuals-anleitungen-download-kostenlos/2230368-kenwood-mdx-g2-h-service-manual-anleitung-pdf-download HTTP/1.0" 500 30899 "-" "Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; bingbot/2.0; +Bing Webmaster Tools) Chrome/103.0.5060.134 Safari/537.36"
 
If it is a static resource: Have you also checked proxy_error_log?
And there could be another reason, maybe a defective hard link between the logs. When you look into the "Logs" link in your Plesk graphical user interface, do you see more entries on that error there? It should be a combined log that shows all entries at once.
