A 500 Internal Server Error is an HTTP status code indicating a generic server-side issue preventing the request from being fulfilled. It usually shows up as a vague “Internal Server Error” notification, necessitating backend analysis to determine and fix the underlying issue.

In this guide, we’ll walk you through how to fix 500 internal server errors and get your site back up and running smoothly. Let’s dive in!

What Causes a 500 Internal Server Error?

A 500 Internal Server Error is a server-side issue that disrupts your website’s functionality, leaving visitors staring at a broken page.

To resolve it effectively, it’s essential to understand the potential causes:

  • Misconfigured .htaccess files
  • Faulty PHP scripts or plugins
  • Exhausted server resources (e.g., memory limits)
  • Incorrect file permissions
  • Database connection failures

Pinpointing the exact cause requires systematic troubleshooting, but understanding these common triggers will help you tailor your approach based on your technical expertise.

How to Fix 500 Internal Server Error: Step-by-Step Process

Resolving a 500 error demands systematic troubleshooting, whether you’re a tech-savvy pro or a time-strapped creative. Start with simple fixes like refreshing cached data, then escalate to advanced diagnostics like server log analysis.

Below, we’ve curated a clear, beginner-friendly roadmap to tackle this error. Follow these steps to restore your site’s functionality and reinforce your digital resilience—no coding expertise required:

1. Check Your Server Logs

Server logs are your first and most valuable clue in diagnosing a 500 Internal Server Error. These logs can help identify specific issues like faulty scripts or misbehaving plugins. To access them:

  • Log in to your cPanel dashboard (or equivalent hosting control panel).
  • Navigate to Metrics > Errors (or the error logs section).
  • Review recent entries for details, such as PHP fatal errors or missing files.

Examining these logs often highlights the root cause, allowing you to take targeted action.

2. Refresh and Clear Your Cache

Sometimes, the error is temporary. Refresh the page (Ctrl + F5) to bypass cached data. If using a CMS like WordPress, clear your site’s cache via plugins like W3 Total Cache or your hosting dashboard.

3. Deactivate Plugins or Themes

A misbehaving plugin or theme is a common culprit. For WordPress users:

  1. Access your site via FTP (use FileZilla) or cPanel File Manager.
  2. Rename the /plugins/ folder to /plugins.deactivate/.
  3. Refresh your site—if it loads, reactivate plugins one by one to identify the issue.

4. Review Your .htaccess File

A corrupted .htaccess file can trigger 500 errors. To fix this:

  1. Open File Manager in cPanel.
  2. Locate .htaccess in your root directory.
  3. Rename it to.htaccess.bak.
  4. Refresh your site. If resolved, generate a new .htaccess file via your CMS.

5. Adjust File Permissions

Incorrect permissions prevent servers from reading critical files. Ideal settings:

  • Folders: 755
  • Files: 644

Use cPanel’s File Manager or an FTP client to adjust permissions.

6. Increase PHP Memory Limit

Resource-heavy plugins or themes may exceed default limits. To increase PHP memory:

  1. Edit your php.ini file (locate via cPanel).
  2. Add: memory_limit = 256M
  3. Save and restart your server.

For WordPress, add define(‘WP_MEMORY_LIMIT’, ‘256M’); to wp-config.php.

7. Check Database Connections

A corrupted database or broken connection can cause 500 errors. Use phpMyAdmin (via cPanel) to:

  1. Repair database tables.
  2. Ensure your wp-config.php (WordPress) has correct database credentials.

8. Contact Your Hosting Provider

Even the smartest professionals encounter stubborn server issues. If DIY fixes fail, escalating to experts saves time and stress. 

When contacting your hosting provider, provide as much detail as possible. Share any error logs or steps you’ve already taken and describe the issue clearly. This will help their support team identify and resolve the issue quickly, minimising downtime.

Pro Tip: Many hosting providers offer live chat support, which often results in faster response times than email or ticket submissions. Use this option for urgent issues to minimise downtime and get real-time guidance through troubleshooting steps.

Proactive Measures to Avoid Future Errors

A 500 error often stems from outdated plugins, poor resource management, or infrequent maintenance—issues that strategic planning can prevent.

  • Backups: Enable automated backups.
  • Updates: Regularly update CMS, plugins, and themes.
  • Resource Monitoring: Upgrade hosting if nearing limits.

For SMEs and startups, server errors can hinder revenue and damage SEO.
