A 500 error, also known as an "Internal Server Error", is an HTTP status code indicating that the web server encountered a problem that prevented it from fulfilling your request.
Explanation of 500 Error
When a browser requests a site, the server processes the request and responds. A 500 error means something went wrong on the server’s side, but the server cannot specify the exact problem. This is a generic "catch-all" for server-side issues like misconfigurations, failed scripts, or resource exhaustion.
Common Causes
- Corrupted browser cache or cookies
- Syntax errors, incorrect permissions, or problems with the .htaccess file
- Incorrect or corrupted database credentials or files
- Exhausted PHP memory limit or PHP version problems
- Faulty plugins, themes, or corrupted web files (especially for WordPress sites)
- Server overload or temporary glitches
Impact
Users experiencing a 500 error cannot access the website until the issue is resolved. Prolonged errors can affect user experience and search engine rankings.
What Can Be Done
As a website visitor:
- Try refreshing the site or clearing your browser cache.
As a website owner or administrator:
- Check for script errors, plugin/theme issues, or misconfigured files and permissions.
- Review server error logs for more technical details.
A 500 error generally requires technical fixes by the website administrator, and usually does not signal a permanent problem.
