Fix My Website: Complete WordPress Troubleshooting Guide

If you are looking for how to fix your WordPress website, you are not alone. Thousands of website owners face technical issues every day, from the dreaded white screen of death to database connection errors. The good news is that most of these problems have known solutions.

In our WordPress support service, we solve these problems daily. In this guide, we share the exact steps we follow to diagnose and repair the most common issues.

Initial Diagnosis: Identify the Problem

Before trying to fix anything, you need to understand what is failing. Ask yourself these questions:

• Is the site completely down or are only some features not working?
• Does the problem occur on all pages or only some?
• Did you make any recent changes (update, new plugin, code edit)?
• Does the problem affect all users or just you?
• Do you see any specific error message?

The 10 Most Common Problems and How to Fix Them

1. White Screen of Death (WSOD)

The white screen is one of the most frustrating problems because it shows no error message. It is generally caused by a PHP error or exceeded memory limit.

Step-by-step solution:

1. Enable debug mode by adding define('WP_DEBUG', true); to wp-config.php
2. Increase PHP memory limit: define('WP_MEMORY_LIMIT', '256M');
3. Deactivate all plugins via FTP (rename the /plugins/ folder to /plugins_disabled/)
4. Switch to the default theme (Twenty Twenty-Four) via database if necessary
5. Reactivate plugins one by one to identify the culprit

2. Error Establishing a Database Connection

This error means WordPress cannot connect to your MySQL database. Common causes:

• Incorrect credentials in wp-config.php
• Database server is down
• Corrupted database
• Connection limit exceeded on hosting

Solution: Verify the database credentials in wp-config.php (DB_NAME, DB_USER, DB_PASSWORD, DB_HOST). Contact your host if the database server is down. For corrupted databases, add define('WP_ALLOW_REPAIR', true); and visit /wp-admin/maint/repair.php.

3. 500 Internal Server Error

A generic server error that can be caused by multiple factors:

• Corrupt .htaccess file
• Insufficient PHP memory limit
• Incompatible plugin or theme
• Incompatible PHP version

Solution: Rename .htaccess via FTP, then regenerate permalinks from Settings. If that doesn't work, deactivate plugins and increase memory limit.

4. 404 Errors on All Pages (Except Homepage)

If your homepage loads but all other pages return a 404 error, the problem is usually the permalinks.

Solution: Go to Settings > Permalinks and click "Save Changes" without modifying anything. This regenerates the .htaccess file. If you don't have admin access, create a new .htaccess via FTP with WordPress's default rewrite rules.

5. Hacked Site or Malware

Signs that your site has been compromised:

• Redirects to suspicious sites
• Spam content visible on your site
• Google flags your site as dangerous
• Unknown administrator users
• Unknown files on your server

Solution: Scan with Wordfence or Sucuri, remove malicious files, restore from a clean backup if possible, change all passwords, and update everything. For severe cases, we recommend contacting professionals.

6. Slow WordPress

A slow site is not just annoying, it affects your SEO and conversions. Common causes: low-quality hosting, heavy plugins, unoptimized images, and lack of caching.

Solution: Install a caching plugin, optimize images, reduce unnecessary plugins, and consider upgrading your hosting. Read our complete speed optimization guide.

7. "Briefly Unavailable for Scheduled Maintenance" Error

This error appears when an update did not complete correctly and WordPress was left in maintenance mode.

Solution: Connect via FTP and delete the .maintenance file from the WordPress root. Then complete any pending updates.

8. File Upload Issues

If you can't upload images or files, it may be due to incorrect permissions or size limits.

Solution: Verify that the /wp-content/uploads/ folder has 755 permissions. For large files, increase the limits in php.ini: upload_max_filesize and post_max_size.

9. SSL/HTTPS Errors

Mixed content where some resources load over HTTP and others over HTTPS.

Solution: Use the Really Simple SSL plugin or manually update URLs in the database. Verify that the URLs in Settings > General use HTTPS.

10. Plugin Conflicts

Two plugins trying to do the same thing can cause errors. Deactivate all plugins and reactivate them one by one to identify the conflict. Once identified, look for a compatible alternative.

When to Call a Professional

Try to solve the problem yourself if you have basic technical knowledge. But call a professional when:

• Your site has been hacked and you don't know which files were compromised
• You have tried the basic solutions without success
• The problem involves the database and you don't have MySQL experience
• Your site is critical to your business and you need a quick solution
• You don't feel comfortable editing server files
