Unlike a 404 error that tells you a page is missing, a 500 error gives no specific details. That vagueness makes it one of the most frustrating errors to troubleshoot.<\/p>\n\n\n\n<p>The good news: most 500 errors trace back to a handful of common causes. This guide walks through each one with specific steps to identify the problem and get your site back online.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Causes a 500 Internal Server Error?<\/h2>\n\n\n\n<p>The server generates a 500 error when it encounters an unexpected condition that prevents it from completing a request. According to <a href=\"https:\/\/developer.mozilla.org\/en-US\/docs\/Web\/HTTP\/Status\/500\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Mozilla Developer Network documentation<\/a>, this status code indicates a server-side problem rather than an issue with the client\u2019s request.<\/p>\n\n\n\n<p>The most common causes include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Corrupted or misconfigured .htaccess file<\/strong>: A single syntax error in this file can bring down your entire site.<\/li>\n\n\n\n<li><strong>PHP errors<\/strong>: Syntax mistakes, deprecated functions, or uncaught exceptions in PHP code.<\/li>\n\n\n\n<li><strong>PHP version incompatibility<\/strong>: Scripts or plugins built for older PHP versions may fail on newer releases (or vice versa).<\/li>\n\n\n\n<li><strong>Exhausted PHP memory limit<\/strong>: Scripts that exceed the allocated memory are terminated.<\/li>\n\n\n\n<li><strong>Incorrect file permissions<\/strong>: Files set to 777 (world-writable) trigger security restrictions.<\/li>\n\n\n\n<li><strong>Plugin or theme conflicts<\/strong>: WordPress plugins can clash with each other or with the core.<\/li>\n\n\n\n<li><strong>Database connection failures<\/strong>: Incorrect credentials or an unreachable database server.<\/li>\n\n\n\n<li><strong>Corrupted WordPress core files<\/strong>: Missing or damaged files from failed updates.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Step 1: Check the Error Logs<\/h2>\n\n\n\n<p>Error logs are your first source of information.

memory errors after increasing the limit, investigate which plugin or process is consuming excessive resources.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 6: Deactivate Plugins (WordPress)<\/h2>\n\n\n\n<p>Plugin conflicts are among the most common causes of WordPress 500 errors. A recent update, a poorly coded plugin, or two plugins competing for the same resources can all trigger failures.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">If You Can Access the Dashboard<\/h3>\n\n\n\n<ol class=\"wp-block-list article_list\">\n<li>Go to <strong>Plugins &gt; Installed Plugins<\/strong>.<\/li>\n\n\n\n<li>Select all plugins and choose <strong>Deactivate<\/strong> from the Bulk Actions menu.<\/li>\n\n\n\n<li>Reload your site.<\/li>\n<\/ol>\n\n\n\n<p>If the error clears, reactivate plugins one at a time to identify the culprit.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">If You Cannot Access the Dashboard<\/h3>\n\n\n\n<ol class=\"wp-block-list article_list\">\n<li>Connect to your site via SFTP or File Manager.<\/li>\n\n\n\n<li>Navigate to <code>wp-content\/<\/code>.<\/li>\n\n\n\n<li>Rename the <code>plugins<\/code> folder to <code>plugins_disabled<\/code>.<\/li>\n\n\n\n<li>Reload your site.<\/li>\n<\/ol>\n\n\n\n<p>If the site works, rename the folder back to <code>plugins<\/code> and then rename individual plugin folders one at a time to isolate the problem.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 7: Switch to a Default Theme (WordPress)<\/h2>\n\n\n\n<p>A corrupted or incompatible theme can cause 500 errors, especially after updates or PHP version changes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">If You Can Access the Dashboard<\/h3>\n\n\n\n<ol class=\"wp-block-list article_list\">\n<li>Go to <strong>Appearance &gt; Themes<\/strong>.<\/li>\n\n\n\n<li>Activate a default theme like Twenty Twenty-Four.<\/li>\n\n\n\n<li>Reload your site.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">If You Cannot Access the Dashboard<\/h3>\n\n\n\n<ol class=\"wp-block-list article_list\">\n<li>Connect via SFTP or File Manager.<\/li>\n\n\n\n<li>Navigate to <code>wp-content\/themes\/<\/code>.<\/li>\n\n\n\n<li>Rename your active theme\u2019s folder (e.g., <code>theme-name<\/code> to <code>theme-name_disabled<\/code>).<\/li>\n\n\n\n<li>WordPress automatically activates a default theme if one is available.<\/li>\n<\/ol>\n\n\n\n<p>If the site loads, the theme was the issue. Contact the theme developer or switch to a different theme.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 8: Re-upload WordPress Core Files<\/h2>\n\n\n\n<p>Corrupted core files from interrupted updates or file transfer errors can cause 500 errors.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Safe Re-upload Process<\/h3>\n\n\n\n<ol class=\"wp-block-list article_list\">\n<li>Download a fresh copy of WordPress from <a href=\"https:\/\/wordpress.org\/download\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">wordpress.org<\/a>.<\/li>\n\n\n\n<li>Extract the ZIP file on your computer.<\/li>\n\n\n\n<li>Delete the <code>wp-content<\/code> folder from the extracted files (to preserve your content).<\/li>\n\n\n\n<li>Upload the remaining files to your site via SFTP, overwriting existing files.<\/li>\n<\/ol>\n\n\n\n<p>This replaces potentially corrupted core files without affecting your themes, plugins, or media.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 9: Verify Database Connection<\/h2>\n\n\n\n<p>WordPress stores a connection error page for database issues, but misconfigurations can sometimes trigger a generic 500 error instead.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Check wp-config.php Credentials<\/h3>\n\n\n\n<p>Open <code>wp-config.php<\/code> and verify these lines:<\/p>\n\n\n\n<div class=\"wp-block-kevinbatdorf-code-block-pro\" data-code-block-pro-font-family=\"Code-Pro-JetBrains-Mono-NL.ttf\" style=\"font-size:clamp(16px, 1rem, 24px);font-family:Code-Pro-JetBrains-Mono-NL,ui-monospace,SFMono-Regular,Menlo,Monaco,Consolas,monospace;line-height:clamp(26px, 1.625rem, 39px);--cbp-tab-width:2;tab-size:var(--cbp-tab-width, 2)\"><span role=\"button\" tabindex=\"0\" style=\"color:#e1e4e8;display:none\" aria-label=\"Copy\" class=\"code-block-pro-copy-button\"><pre class=\"code-block-pro-copy-button-pre\" aria-hidden=\"true\"><textarea class=\"code-block-pro-copy-button-textarea\" tabindex=\"-1\" aria-hidden=\"true\" readonly>define('DB_NAME', 'your_database_name');\ndefine('DB_USER', 'your_database_user');\ndefine('DB_PASSWORD', 'your_password');\ndefine('DB_HOST', 'localhost');<\/textarea><\/pre><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" style=\"width:24px;height:24px\" fill=\"none\" viewbox=\"0 0 24 24\" stroke=\"currentColor\" stroke-width=\"2\"><path class=\"with-check\" stroke-linecap=\"round\" stroke-linejoin=\"round\" d=\"M4.5 12.75l6 6 9-13.5\"><\/path><path class=\"without-check\" stroke-linecap=\"round\" stroke-linejoin=\"round\" d=\"M16.5 8.25V6a2.25 2.25 0 00-2.25-2.25H6A2.25 2.25 0 003.75 6v8.25A2.25 2.25 0 006 16.5h2.25m8.25-8.25H18a2.25 2.25 0 012.25 2.25V18A2.25 2.25 0 0118 20.25h-7.5A2.25 2.25 0 018.25 18v-1.5m8.25-8.25h-6a2.25 2.25 0 00-2.25 2.25v6\"><\/path><\/svg><\/span><pre class=\"shiki github-dark\" style=\"background-color: #24292e\" tabindex=\"0\"><code><span class=\"line\"><span style=\"color: #79B8FF\">define<\/span><span style=\"color: #E1E4E8\">(<\/span><span style=\"color: #9ECBFF\">'DB_NAME'<\/span><span style=\"color: #E1E4E8\">, <\/span><span style=\"color: #9ECBFF\">'your_database_name'<\/span><span style=\"color: #E1E4E8\">);<\/span><\/span>\n<span class=\"line\"><span style=\"color: #79B8FF\">define<\/span><span style=\"color: #E1E4E8\">(<\/span><span style=\"color: #9ECBFF\">'DB_USER'<\/span><span style=\"color: #E1E4E8\">, <\/span><span style=\"color: #9ECBFF\">'your_database_user'<\/span><span style=\"color: #E1E4E8\">);<\/span><\/span>\n<span class=\"line\"><span style=\"color: #79B8FF\">define<\/span><span style=\"color: #E1E4E8\">(<\/span><span style=\"color: #9ECBFF\">'DB_PASSWORD'<\/span><span style=\"color: #E1E4E8\">, <\/span><span style=\"color: #9ECBFF\">'your_password'<\/span><span style=\"color: #E1E4E8\">);<\/span><\/span>\n<span class=\"line\"><span style=\"color: #79B8FF\">define<\/span><span style=\"color: #E1E4E8\">(<\/span><span style=\"color: #9ECBFF\">'DB_HOST'<\/span><span style=\"color: #E1E4E8\">, <\/span><span style=\"color: #9ECBFF\">'localhost'<\/span><span style=\"color: #E1E4E8\">);<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n<p>Confirm these match the database credentials in cPanel &gt; <a href=\"https:\/\/www.inmotionhosting.com\/support\/edu\/cpanel\/manage-mysql-database-in-phpmyadmin\/\">MySQL Databases<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Test Database Connectivity<\/h3>\n\n\n\n<p>In cPanel, go to <strong>phpMyAdmin<\/strong> and try logging in to your database.
