500 Internal Server Error? What It Means and What You Can Do

By /

Problem Statement (Clear & Direct)

You try to load a website, but instead of content, you see a 500 Internal Server Error.

This error means the website’s server ran into a problem and couldn’t complete the request.

Common Symptoms

  • “500 Internal Server Error” message

  • “HTTP Error 500”

  • Blank page with a server error notice

  • Website loads sometimes, fails other times

  • Admin pages won’t open

What a 500 Internal Server Error Means

A 500 error is a server-side error, not a browser or device issue.

It means:

  • The server is online

  • The request reached the server

  • Something went wrong internally before the page could load

Unlike a 404 error, the page exists, but the server can’t process it.

Common Causes

A 500 error can be caused by:

  • Plugin or theme conflicts

  • Corrupted .htaccess file

  • PHP memory limits

  • Server misconfiguration

  • File permission issues

  • Failed updates

Step-by-Step Fixes

Step 1: Refresh and Try Another Page

Start simple:

  • Reload the page

  • Try a different page on the site

If only one page fails, the issue may be isolated.

Step 2: Clear Browser Cache

Cached errors can persist even after a fix.

  • Clear browser cache

  • Open the site in a private/incognito window

If the page loads, the issue was temporary.

Step 3: Disable Plugins (WordPress Sites)

Plugin conflicts are a top cause.

If you can access the dashboard:

  • Disable all plugins

  • Reload the site

  • Re-enable plugins one at a time

If the site loads after disabling plugins, you’ve found the cause.

Step 4: Check the .htaccess File

A corrupted .htaccess file can trigger a 500 error.

  • Rename .htaccess to .htaccess_old

  • Reload the website

  • If it works, regenerate a new .htaccess file

Step 5: Increase PHP Memory Limit

Some sites fail when memory runs out.

  • Increase PHP memory limit in hosting settings

  • Restart services if required

This often fixes 500 errors after updates.

Step 6: Contact Hosting Support

If none of the above works:

  • Server logs need review

  • Configuration issues may exist

  • Permissions or system errors may be present

Hosting support can see errors you can’t.

When a 500 Error Is Serious

A 500 error needs attention if:

  • The site is completely inaccessible

  • Admin access is blocked

  • Errors appear after every update

  • Search engines can’t crawl the site

Persistent 500 errors affect SEO and trust.

When This Isn’t a DIY Fix

If this issue continues across multiple devices or networks, the problem is likely outside your local setup. At that point, contacting your hosting provider, ISP, or a website support service is the next step.

Final Tip

A 500 Internal Server Error is frustrating, but it’s usually fixable.

Most cases come down to:

  • Plugins

  • Configuration

  • Memory limits

Fix it early to avoid downtime and ranking loss.
