WordPress powers millions of websites thanks to its flexibility and ease of use. However, even the most robust platforms can face occasional issues. Below are some of the most common WordPress problems and practical ways to resolve them efficiently.

This issue presents a completely blank screen with no error message, making it tricky to diagnose.

Common Causes

• Plugin or theme conflicts

• PHP errors

• Memory exhaustion

How to Fix

• Deactivate all plugins: Use FTP or cPanel to disable all plugins. Reactivate them one by one to identify the cause.

• Switch to a default theme: Temporarily activate a theme like Twenty Twenty-Three.

• Increase memory limit: Add the following line to wp-config.php:

2. Slow Website Performance

A slow website can hurt both user experience and search engine rankings.

Common Causes

• Large, unoptimized images

• Too many active plugins

• Low-quality hosting

How to Fix

• Optimize images: Use tools like Smush or TinyPNG.

• Reduce plugin use: Deactivate and remove unnecessary plugins.

• Enable caching: Install a caching plugin such as WP Super Cache.

• Upgrade your hosting plan: Choose a provider that offers WordPress-optimized hosting.

3. Hacked Website or Malware Infection

Security breaches can damage your website’s credibility and functionality.

Signs of a Hacked Site

• Redirects to suspicious sites

• Unknown users in your dashboard

• Security warnings from browsers or Google

How to Fix

• Run a malware scan: Use plugins like Wordfence or Sucuri.

• Restore a backup: If available, roll back to a clean backup version.

• Strengthen security: Enable two-factor authentication, update all credentials, and use a firewall.

4. Database Connection Errors

This error prevents your site from loading and usually shows as:
“Error Establishing a Database Connection.”

Common Causes

• Incorrect database credentials

• Corrupted database

How to Fix

• Repair the database: Use phpMyAdmin or add this line to wp-config.php:

• Contact your host: If the problem persists, your hosting provider may need to intervene.

5. Plugin and Theme Conflicts

Conflicts between themes and plugins can break functionality or design.

How to Fix

• Disable recent changes: Undo recent updates or installations.

• Update everything: Ensure WordPress core, themes, and plugins are up to date.

• Use a staging site: Test changes in a safe environment before going live.

6. 500 Internal Server Error

A common yet vague error, often linked to misconfigurations.

Common Causes

• Corrupted .htaccess file
