How to Fix 500 Internal Server Error and Server Too Busy: A Simple Guide
The dreaded 500 Internal Server Error can make any website visitor or admin frustrated. It’s a common issue that signals something went wrong on the server's side, but don't worry—there are clear steps to fix it! Whether you’re seeing this error while browsing the web or on your own website, I’ll break it down for you in simple, understandable terms.
In this guide, we’ll also tackle the "Server Too Busy" error, which often occurs when too many users are trying to access a website at once. Let’s dive in and discover how to resolve these issues quickly!
What is a 500 Internal Server Error?
A 500 Internal Server Error means that something has gone wrong on the website’s server, but the server doesn’t provide specific details about the issue. It can happen for various reasons, from incorrect code to server overload, and it affects the website’s functionality, preventing it from loading properly.
You might see messages like:
- "500 Internal Server Error"
- "HTTP Error 500"
- "500 - Server Error"
- "Internal Server Error"
This is an error from the server side, not your browser or device.
What Causes the 500 Internal Server Error?
A 500 error can be triggered by many things, but here are some common causes:
- Corrupted .htaccess File: This configuration file, found in many web servers, can cause the error if it’s incorrectly modified.
- Exhausted PHP Memory: If your website runs out of memory, it can trigger a 500 error.
- Plugin or Theme Issues: Especially on CMS platforms like WordPress, a faulty plugin or theme can cause server errors.
- Permissions Problems: Incorrect file or folder permissions on the server can block access and cause the error.
- Server Overload: When too many users try to access a website at the same time, the server might get overloaded, triggering the "Server Too Busy" error.
How to Fix a 500 Internal Server Error?
1. Refresh the Page
The simplest step is to refresh your browser. Sometimes, the error is temporary, and reloading can fix the issue.
2. Clear Browser Cache
If you’re seeing the error on multiple websites, your browser's cache might be causing the problem. Try clearing it by:
- Going to your browser settings.
- Navigating to Privacy & Security.
- Clearing your cached data and cookies.
3. Check the Server Logs
If you're running the website, look at your server logs for any clues. Server logs will give you more information on what caused the error.
4. Fix the .htaccess File
For websites running on Apache, a corrupted .htaccess file could be the culprit. Rename the current .htaccess file to something like .htaccess_backup and refresh your website. If it works, regenerate a clean .htaccess file by updating your website’s permalinks.
5. Increase PHP Memory Limit
If the error occurs due to low memory, increasing your PHP memory limit could solve the issue. Contact your hosting provider or modify the php.ini file to set a higher memory limit.
6. Disable Plugins and Themes
For WordPress users or similar CMS platforms, try deactivating all your plugins and switch to the default theme. Reactivate them one by one to see which one might be causing the error.
7. Correct File Permissions
Incorrect permissions can prevent server access, causing the error. Files should generally have 755 or 644 permissions. If you're not sure how to change them, consult your hosting provider.
Fixing the "Server Too Busy" Error
The "Server Too Busy" error occurs when the website’s server is handling too many requests. This usually happens when traffic spikes unexpectedly. Here are some steps to fix it:
1. Increase Server Resources
If your website experiences high traffic regularly, consider upgrading your hosting plan to handle the load.
2. Enable Caching
By using caching techniques like CDNs (Content Delivery Networks) or caching plugins (for WordPress), you can reduce the load on your server, preventing the "Server Too Busy" error.
3. Optimize Your Website
Compress images, minimize code, and optimize your database to reduce the strain on your server.
4. Check Your Server Logs
Again, the server logs might show you if any specific resources are causing the overload, allowing you to adjust or fix the issues accordingly.

2. What is the cause of HTTP 500 internal server error?
