Common WordPress Website Issues and How to Solve Them

WordPress is one of the most popular and versatile content management systems (CMS) globally, powering millions of websites. While it offers immense flexibility and ease of use, users often encounter various issues during development and maintenance. Understanding these common problems and their solutions can save time, improve website performance, and ensure a seamless user experience. Below, we explore common WordPress issues and provide actionable solutions.

1. White Screen of Death (WSOD)

The White Screen of Death is a common WordPress error where a blank white screen appears instead of your website. This issue usually stems from plugin conflicts, theme issues, or memory limits.

Solution:

• Increase PHP Memory Limit: Edit your wp-config.php file and add:define('WP_MEMORY_LIMIT', '256M');
• Disable Plugins: Use FTP or File Manager to rename the plugins folder temporarily. This will deactivate all plugins. Rename it back and activate plugins one by one to identify the culprit.
• Switch to a Default Theme: Rename your active theme folder via FTP to switch to a default theme like Twenty Twenty-One.

2. Slow Website Performance

A slow website can lead to poor user experience and negatively impact SEO rankings. Common reasons include unoptimized images, excessive plugins, or poorly configured hosting.

Solution:

• Optimize Images: Use plugins like Smush or ShortPixel to compress images without losing quality.
• Leverage Caching: Install caching plugins like WP Super Cache or W3 Total Cache.
• Use a Content Delivery Network (CDN): Services like Cloudflare or BunnyCDN can distribute your content globally, reducing load times.
• Upgrade Hosting: Consider switching to a WordPress-optimized hosting provider like SiteGround or WP Engine.

3. Error Establishing a Database Connection

This error occurs when WordPress cannot connect to the database. It might result from incorrect credentials, a corrupted database, or server issues.

Solution:

• Check Database Credentials: Verify your wp-config.php file for correct DB_NAME, DB_USER, and DB_PASSWORD values.
• Repair Database: Add the following line to wp-config.php, then navigate to yourdomain.com/wp-admin/maint/repair.php:define('WP_ALLOW_REPAIR', true);Run the repair tool and remove the line afterward.
• Contact Hosting Provider: If credentials are correct and the issue persists, contact your hosting provider for assistance.

4. WordPress Login Issues

Users sometimes face login problems due to incorrect URLs, corrupted .htaccess files, or plugin conflicts.

Solution:

• Reset Password: Use the “Forgot Password” option to reset your credentials.
• Correct Login URL: If you’ve customized the login URL, ensure it’s correct. Check your security plugin settings if you’ve used one.
• Deactivate Security Plugins: Use FTP to deactivate plugins temporarily by renaming the plugin folder.
• Regenerate .htaccess File: Rename the .htaccess file and create a new one by re-saving permalinks in the WordPress dashboard.

5. 404 Page Not Found Errors

404 errors typically occur when permalinks are broken or pages are deleted without proper redirection.

Solution:

• Resave Permalinks: Go to Settings > Permalinks and click “Save Changes” without modifying anything.
• Redirect Deleted Pages: Use plugins like Redirection to set up 301 redirects for removed pages.
• Check .htaccess File: Ensure the .htaccess file contains the correct rewrite rules for WordPress:# BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress

6. WordPress Stuck in Maintenance Mode

If a WordPress update is interrupted, the site might remain in maintenance mode, displaying a message like “Briefly unavailable for scheduled maintenance. Check back in a minute.”

Solution:

• Remove .maintenance File: Access your website’s root directory via FTP or File Manager and delete the .maintenance file.
• Retry Update: Log in to your WordPress dashboard and retry the update process.

7. Plugin or Theme Compatibility Issues

Solution:

• Update Plugins and Themes: Ensure all plugins and themes are updated to their latest versions.
• Check Compatibility: Use tools like PHP Compatibility Checker to ensure compatibility with your WordPress version.
• Rollback Updates: If an update causes issues, use a plugin like WP Rollback to revert to the previous version.

Solution:

• Increase Memory Limit: Edit your wp-config.php file and add:define('WP_MEMORY_LIMIT', '256M');
