Common WordPress Errors: Fixing the Most Frequent Website Issues Step-by-Step

Introduction

Managing a WordPress website is one of the easiest ways to build an online presence, whether you’re starting a blog, launching a business, or selling digital products. But even the most experienced users sometimes run into unexpected problems. From White Screen of Death to 500 errors, these disruptions can affect your site’s performance, SEO, and user experience.

Fortunately, most Common WordPress errors are easy to fix—if you know what you’re looking for.

This comprehensive guide walks you through the most frequent issues, real-world solutions, and expert tips that will help you get your site back up and running quickly.

Common WordPress Errors from Plugin Conflicts

One of the most frequent causes of WordPress errors is a conflict between plugins.

Anecdote: A client once installed three different security plugins that blocked each other’s scripts. The site kept logging users out and refused to save settings. The fix? Deactivate each plugin one-by-one until the culprit was found.

How to Fix Plugin Conflicts:

1. Connect to your server via FTP or File Manager in cPanel.
2. Go to /wp-content/ and rename the plugins folder to plugins_backup.
3. Refresh your site. If it loads, the issue is with one of the plugins.
4. Rename the folder back and activate plugins one at a time to isolate the problem.

Common WordPress Errors Caused by Theme Compatibility

Poorly coded or outdated themes often result in layout problems, broken navigation, or total site failure.

Common WordPress Errors: Error Establishing a Database Connection

This is one of the most alarming errors — your entire site is down and shows:

“Error establishing a database connection”

This means WordPress can’t communicate with your database.

How to Fix Database Errors:

1. Open wp-config.php and double-check: phpCopyEditdefine('DB_NAME', 'your_database_name'); define('DB_USER', 'your_username'); define('DB_PASSWORD', 'your_password'); define('DB_HOST', 'localhost');
2. Add the following to repair the database: phpCopyEditdefine('WP_ALLOW_REPAIR', true); Visit: https://yoursite.com/wp-admin/maint/repair.php
3. If that doesn’t help, contact your host to verify database status.

Common WordPress Errors During Core Updates

When an update fails or is interrupted, WordPress might get stuck in maintenance mode.

How to Exit Maintenance Mode:

1. Use FTP to access your site’s root directory
2. Delete the .maintenance file
3. Reload your website

This instantly brings your site back online.

Common WordPress Errors Involving Internal Server Problems

A 500 Internal Server Error is vague and frustrating.

What Causes It?

• Corrupt .htaccess file
• Exhausted PHP memory
• Broken plugin or theme

How to Fix It:

1. Rename .htaccess to .htaccess_old
2. Go to Settings > Permalinks in your admin panel and click Save Changes
3. Increase PHP memory by editing wp-config.php: phpCopyEditdefine('WP_MEMORY_LIMIT', '256M');

Common WordPress Errors: Login Redirect Loop

This happens when WordPress repeatedly redirects you back to the login screen after successful login.

How to Fix It:

• Clear browser cache and cookies
• Edit wp-config.php: phpCopyEditdefine('WP_HOME','https://yourdomain.com'); define('WP_SITEURL','https://yourdomain.com');
• Rename the plugins folder via FTP to deactivate all plugins temporarily

Common WordPress Errors from Broken Permalinks

Common WordPress Errors with Media Uploads and Image Display

If you’re getting “HTTP error” during upload or images aren’t showing on your site, it’s likely due to incorrect file permissions or path issues.

Steps to Fix Media Upload Issues:

• Set correct file permissions:
  Folders: 755, Files: 644
• Ensure correct upload path in Settings > Media

Common WordPress Errors with Email Not Sending

If contact form messages or user registration emails are not reaching you, it’s likely an SMTP configuration issue.

How to Set Up SMTP Email:

1. Install WP Mail SMTP plugin
2. Configure with Gmail, SendGrid, or your host’s SMTP
3. Send a test email to verify

Common WordPress Errors from SSL Issues

Improper SSL setup can lead to “Not secure” warnings or mixed content errors.

Steps to Fix SSL Errors:

• Install Really Simple SSL
• Update URLs in the WordPress settings and database
• Use Let’s Encrypt for a free SSL certificate
