Most Common WordPress Errors and How to Fix Them

How to Fix the White Screen of Death

The White Screen of Death (WSoD) is a frustrating error that leaves your website showing nothing but a blank page. This can disrupt your business and harm customer trust.

Common Causes of White Screens

The WSoD usually happens due to these issues:

• PHP Memory Limit Reached: Your site runs out of allocated memory.
• Plugin or Theme Conflicts: Errors or incompatibilities between WordPress components.
• Database Connection Errors: Problems accessing or reading your WordPress database.

Steps to Fix White Screen Issues

If you encounter the WSoD, try these troubleshooting methods:

1. Enable Debug Mode
   Modify your wp-config.php file to display error messages. Add these lines:

   define('WP_DEBUG', true);
   define('WP_DEBUG_LOG', true);
   define('WP_DEBUG_DISPLAY', true);
   

2. Increase PHP Memory Limit
   Raise the memory limit by adding this to your wp-config.php file:

   define('WP_MEMORY_LIMIT', '256M');
   

3. Identify Plugin Problems
   • If you can log in to wp-admin, deactivate all plugins and reactivate them one by one to find the culprit.
   • If you can’t access wp-admin, use FTP to rename the plugins folder. This temporarily disables all plugins.
4. Check Theme Compatibility
   If the admin area is inaccessible, switch to a default WordPress theme (like Twenty Twenty-Three) via FTP to rule out theme-related issues.

After fixing the problem, it’s crucial to take steps to avoid similar issues in the future.

Preventing White Screens

To keep your site running smoothly, adopt these practices:

Regular Maintenance

Additional Tips:

• Test updates on a staging site before applying them to your live site.
• Always use the latest PHP version supported by your host.
• Monitor server resource usage regularly.
• Store backups on separate servers for added security.
• Choose plugins with good reviews and frequent updates.

For WordPress sites running version 5.2 or later, the built-in recovery mode sends emails to administrators when critical errors occur. Keep this feature active to catch and resolve issues quickly.

Database Connection Error Fixes

The "Error Establishing a Database Connection" message is a serious issue that blocks customer access and makes site management impossible. This error needs immediate attention to avoid revenue loss and keep customer trust intact. Below, we’ll cover common reasons for this error and how to fix it.

Why Database Errors Happen

Here are some typical reasons behind database connection errors:

• Incorrect Database Credentials: If you’ve recently migrated your site or changed hosting, the database login details in your wp-config.php file might not match your hosting settings.
• Server Issues: High traffic surges or maintenance by your hosting provider can temporarily disrupt database access.
• Corrupted WordPress Files: Malware infections or failed updates can damage essential WordPress files.
• Database Corruption: Plugin conflicts or system crashes can corrupt database tables.

Steps to Restore Database Access

Follow these steps to resolve a database connection error:

1. Verify Database Credentials
   Check your database settings in cPanel or your hosting dashboard. Compare these settings with the details in your wp-config.php file. Ensure the following match exactly:
   • Database name
   • Username
   • Password
   • Database host
2. Run Database Repair
   Add this line to your wp-config.php file: define('WP_ALLOW_REPAIR', true);. Then, go to yourdomain.com/wp-admin/maint/repair.php in your browser. Run the repair process, and once complete, remove the line from your file.
3. Contact Your Host
   If the above steps don’t work, reach out to your hosting provider. They can:
   • Confirm the database server’s status
   • Check for resource limitations
   • Verify if the MySQL service is running
   • Reset database permissions as needed

Database Care Guidelines

Regular maintenance can help you avoid future database connection errors. Here’s a quick guide:

Additional Tips for Prevention:

• Use a security plugin to block malware.
• Monitor your server’s resource usage.
• Update WordPress core, themes, and plugins regularly.
• Keep a record of your database credentials.
• Store backups on a separate server for added security.

Best Practices for Plugin Management

To avoid future problems, follow these guidelines:

For high-traffic business sites, automated tools like Smart Plugin Manager are worth considering. This tool uses Visual Regression Testing to spot and roll back problematic updates, ensuring your site stays online without interruptions.

Speed Up Your WordPress Site

Slow websites can hurt your bottom line. Amazon estimates that a one-second delay in page loading could cost them $1.6 billion in lost revenue every year. For business websites, improving speed is key to keeping customers engaged and boosting sales.

Identify Speed Issues

Start by checking your site’s performance with these tools:

A site that loads in 1.7 seconds is faster than 75% of websites globally. Use this as your baseline and address any issues the tools highlight to improve your site’s speed.

How to Make Your Site Faster

Here are practical ways to enhance your site’s loading time:

Optimize Your Images
Images make up about 42% of a webpage’s total size. Use the right formats: JPEG for photos, PNG for graphics with transparency, and WebP for modern browsers.

Improve Your Server Setup

• Upgrade to the latest PHP version.
• Enable server-level caching.
• Choose a high-performance hosting provider like Cloudways for better server efficiency.

Use a Content Delivery Network (CDN)
A CDN can reduce load times by serving content from servers closer to your users. Cloudflare‘s free tier is a good starting point.

Leverage Caching Plugins
Caching can significantly speed up your site. Consider these options:

Balancing Speed and Features

While speed is crucial, you don’t want to sacrifice important functionality. Here’s how to strike the right balance:

Keep What Matters
Stick to plugins that are critical for your business. Regularly check their performance and replace heavy plugins with lighter options when possible.

Set Performance Goals
Aim for a homepage load time of under 2 seconds and a TTFB below 0.8 seconds.

WordPress Security Error Prevention

Security breaches can cripple business websites. With WordPress powering over 40% of all websites, it’s often targeted by attackers. This section outlines common vulnerabilities and practical steps to protect your site. While fast loading times improve user experience, strong security safeguards your reputation.
