Server and PHP logs
Identify fatal errors, permission failures, timeouts, resource exhaustion, and configuration problems.
HTTP 500 diagnosis and repair
Fix the WordPress 500 error by finding the server-side failure behind it.
I diagnose Internal Server Errors across WordPress, PHP, .htaccess, plugins, themes, permissions, resource limits, and hosting configuration, then verify the request that originally failed.

Recognize the problem
Where a WordPress 500 error can appear
One symptom does not always confirm a compromise, but several together deserve a careful investigation.
- The entire website returns “500 Internal Server Error”
- Only wp-admin or wp-login.php returns HTTP 500
- Saving a page, form, menu, or settings triggers the error
- Uploading media or importing content fails with status 500
- WooCommerce checkout or an API callback fails
- The error started after editing .htaccess or permalinks
- A plugin or theme update caused the server error
- The website fails intermittently under traffic or resource load
Scope of work
Layers checked during a 500-error diagnosis
The investigation starts with the failing URL and follows the server evidence.
.htaccess and rewrite rules
Repair malformed directives, unsupported options, redirect loops, and conflicting security rules.
Plugins and themes
Isolate code that fails only on a particular admin, frontend, AJAX, REST, or checkout request.
PHP limits and compatibility
Review memory, execution time, extensions, handlers, and version compatibility.
Files and permissions
Check corrupted core files, missing dependencies, ownership, and file or directory permissions.
Request verification
Retest the exact URL or action and confirm the server returns a successful response.
How it works
A clear path from problem to recovery.
- 01
Identify the failing request
Determine whether the error affects every request or only an action, URL, user, or traffic condition.
- 02
Correlate the logs
Match the request time with web-server, PHP, WordPress, proxy, and hosting evidence.
- 03
Repair the failed layer
Correct the code, rule, permission, limit, file, or configuration causing the request to abort.
- 04
Verify response and function
Confirm the HTTP response and the user-facing workflow that depends on it.

About MD PabelCommon questions
Before we start.
Is a WordPress 500 error always caused by a plugin?+
No. Plugins are common causes, but .htaccess rules, PHP compatibility, memory, permissions, corrupted files, web-server configuration, reverse proxies, and hosting resource limits can produce the same status.
Why does only wp-admin show a 500 error?+
Admin-only errors often involve an admin hook, plugin screen, PHP memory demand, security rule, AJAX request, or code that runs only for logged-in users.
Can the site be fixed without reinstalling WordPress?+
Usually, yes. Reinstalling does not fix configuration, database, plugin, theme, permission, or server causes and can make diagnosis harder if done before logs are checked.
