500 Internal Server Error — Causes and Solutions

What does this error mean?

500 Internal Server Error means the server encountered an unexpected condition that prevented it from fulfilling the request. It is typically caused by issues in the website code or server configuration.

Common Causes:

1. Errors in Website Code
PHP syntax errors, infinite loops, or database connection problems.
Solution: Enable error display and check the error_log file.

2. Incorrect File Permissions
Wrong permissions for files or directories.
Recommended values:
Files: 644
Folders: 755

3. .htaccess Errors
Unsupported or incorrect directives.
Solution: Temporarily rename the .htaccess file and check if the site loads.

4. Missing PHP Modules
Modules like mysqli, mbstring, or curl might be required.
Solution: Enable necessary modules in your hosting control panel.

5. Hosting Limits Reached
Such as memory, execution time, or process limits.
Solution: Increase limits in php.ini if possible.

6. Plugin/Theme Conflicts (CMS)
Especially after updates in systems like WordPress.
