Restore the WordPress default files<\/h3>\n\n\n\n<p>Some WordPress files are essential for the platform to establish a connection with the database. If those files are corrupted from a hack or an update malfunction, you\u2019ll need to fix them to stop the database connection error in WordPress.<\/p>\n\n\n\n<p>Thankfully, restoring the default tiles won\u2019t remove your plugins, themes or content.<\/p>\n\n\n\n<p>That said, you may lose certain custom changes you\u2019ve made on your website, so make sure you\u2019ve backed up your WordPress website before proceeding.<\/p>\n\n\n\n<p>To restore the default files of your WordPress website:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Download the default version of WordPress via <a href=\"https:\/\/wordpress.org\/download\/\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/wordpress.org\/download\/<\/a>.<\/li>\n\n\n\n<li>Unzip the file.<\/li>\n\n\n\n<li>Delete the&nbsp;<strong>wp-content folder<\/strong> and the <strong>wp-config-sample.php file<\/strong>.<\/li>\n\n\n\n<li>Use an <a href=\"https:\/\/www.bluehost.com\/blog\/best-ftp-client\/\">FTP client<\/a> to upload the new WordPress files to the main WordPress root.<\/li>\n\n\n\n<li>Proceed with the overwrite.<\/li>\n<\/ul>\n\n\n\n<p>When complete, refresh WordPress and see if the database connection error has resolved.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a><\/a>5.

It happens when the PHP file responsible for processing requests cannot communicate with the database server due to incorrect database login credentials, database corruption, or server issues.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1760440562819\"><strong class=\"schema-faq-question\">How do I check and fix incorrect database login credentials?<\/strong> <p class=\"schema-faq-answer\">You can check your database details by opening the wp-config.php file in your WordPress installation root directory. Verify that the database name, username, password information, and database host are correct. If you recently moved to a new hosting provider, these details might have changed. Update the wp-config.php file with the correct database credentials to fix the error.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1760440652170\"><strong class=\"schema-faq-question\">How can I repair database corruption in WordPress?<\/strong> <p class=\"schema-faq-answer\">WordPress has a built-in repair feature. Add the following code to your wp-config.php file:<br\/>php define(&#8216;WP_ALLOW_REPAIR&#8217;, true);<br\/>Then visit https:\/\/your-site-url.com\/wp-admin\/maint\/repair.php and choose the repair database option. After repairing, remove the code from wp-config.php for security.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1760440673266\"><strong class=\"schema-faq-question\">What should I do if the host&#8217;s database server is down?<\/strong> <p class=\"schema-faq-answer\">If the MySQL server or the web and database server is down or overloaded, WordPress cannot establish a database connection.

Reactivate plugins and themes one by one to identify the culprit.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1760440728141\"><strong class=\"schema-faq-question\">How do I create a new MySQL user and database?<\/strong> <p class=\"schema-faq-answer\">Using your hosting control panel, navigate to the MySQL Databases section. Create a new database, then create a new MySQL user with a strong password. Assign the user to the database with all privileges. Update your wp-config.php file with the new database details.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1760440744220\"><strong class=\"schema-faq-question\">How do I update the WordPress site URL in the database?<\/strong> <p class=\"schema-faq-answer\">Access phpMyAdmin through your hosting control panel, select your WordPress database, then run the following MySQL query:<br\/>mysql UPDATE wp_options SET option_value=&#8217;https:\/\/your-site-url.com&#8217; WHERE option_name=&#8217;siteurl&#8217;;<br\/>Replace https:\/\/your-site-url.com with your actual site URL.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1760440760677\"><strong class=\"schema-faq-question\">What if I need to reboot my local server or web server?<\/strong> <p class=\"schema-faq-answer\">If you manage a local server, VPS, or dedicated server, rebooting the web and database server can clear temporary glitches causing database connection errors.
