Code 500

HTTP 500 (Internal Server Error) is a generic server-side error response indicating that the server encountered an unexpected condition that prevented it from fulfilling the request. It is caused by server misconfigurations, faulty scripts, or database connection failures rather than client-side issues.

HTTP 500 errors appear in server log files and can be detected by Screaming Frog and Google Search Console's Coverage report. Resolving them requires investigating server logs, checking for plugin conflicts in CMS platforms, and ensuring server resource limits (memory, execution time) are properly configured.
