WordPress powers over 43% of all websites on the internet — but like any software, it can sometimes throw up issues that frustrate website owners. The good news? Most common WordPress problems have straightforward solutions.

In this post, we’ll look at the most common WordPress issues and how to fix them yourself (or with the help of a developer). Let’s dive in!

✅ 1. White Screen of Death (WSOD)

Problem:
You visit your website and see nothing but a blank white screen — no error message, no clue.

Why it happens:
Usually due to exhausted memory limits, plugin conflicts, or theme errors.

How to fix it:

• Increase PHP memory limit: Add define('WP_MEMORY_LIMIT', '256M'); to your wp-config.php file.
• Disable all plugins: Rename your /wp-content/plugins/ folder via FTP to something like /plugins_old to deactivate all plugins. If your site comes back, it’s a plugin issue.
• Switch to a default theme: Rename your active theme’s folder; WordPress will fall back to a default theme like Twenty Twenty-Four.
• Enable debugging: Add define('WP_DEBUG', true); in wp-config.php to see error messages.

✅ 2. Error Establishing a Database Connection

Problem:
Your site shows: “Error establishing a database connection.”

Why it happens:
Incorrect database credentials, corrupt database, or an unresponsive server.

How to fix it:

• Check wp-config.php: Make sure your database name, username, password, and host are correct.
• Repair database: Add define('WP_ALLOW_REPAIR', true); to wp-config.php. Visit yoursite.com/wp-admin/maint/repair.php to repair it.
• Contact hosting provider: If your credentials are fine, the database server may be down.

✅ 3. 404 Errors for Posts

Problem:
You get a 404 Not Found error when visiting a post or page.

Why it happens:
Broken permalink structure.

How to fix it:

• Go to Settings → Permalinks, and click “Save Changes” to regenerate .htaccess.
• If that doesn’t work, manually update your .htaccess file with default WordPress rewrite rules.

---

✅ 4. Failed Auto-Update

Problem:
WordPress core, plugins, or theme updates fail.

Why it happens:
Server timeouts, low memory, or file permission issues.

How to fix it:

• Update manually: Download the update and upload via FTP.
• Check file permissions: Folders should be 755, files 644.
• Increase PHP execution time: Add set_time_limit(300); in wp-config.php.

---

✅ 5. Login Page Redirect Loop

Problem:
You can’t log in; the login page keeps refreshing.

Why it happens:
Incorrect site URL or corrupted .htaccess.

How to fix it:

• Clear cookies and cache.
• Check wp-config.php for correct WP_HOME and WP_SITEURL values.
• Rename .htaccess and regenerate permalinks.
• Deactivate all plugins to rule out a conflict.

---

✅ 6. Images Not Uploading

Problem:
You get a file permission error when uploading images.

Why it happens:
Incorrect file permissions on the uploads folder.

How to fix it:

• Set wp-content/uploads folder permission to 755 or 775.
• Use your hosting control panel’s File Manager or an FTP client to adjust.

---

✅ 7. Connection Timed Out

Problem:
Site takes too long to respond and shows a timeout error.

Why it happens:
Heavy plugins, low server resources, or poorly coded themes.

How to fix it:

• Deactivate resource-heavy plugins.
• Increase PHP memory limit.
• Upgrade hosting plan if needed.

---

✅ 8. Mixed Content Warnings After SSL

Problem:
You installed SSL, but browsers show “Not Secure” due to mixed content.

Why it happens:
Some files (images, scripts) still use http instead of https.

How to fix it:

• Use a plugin like Really Simple SSL.
• Run a search and replace for old http:// URLs in the database.
• Update hardcoded links in theme files.
