Why WordPress Errors Happen

Before fixing errors, it helps to understand why they occur:

• Plugin or theme conflicts
• Outdated WordPress core, plugins, or themes
• Incorrect file permissions
• Memory limits and hosting restrictions
• Small mistakes during updates or configuration

Most issues are recoverable, and WordPress usually provides clues if you know where to look.

1. White Screen of Death (WSOD)

What It Looks Like

A completely blank white page on the front end or admin panel.

Common Causes

• Faulty plugin or theme
• PHP memory limit exhausted
• Corrupted WordPress files

How to Fix It (No Developer Needed)

1. Disable all plugins
   • Access your site via File Manager or FTP
   • Rename the plugins folder to plugins-old
   • Reload your site
   • If it works, rename the folder back and activate plugins one by one
2. Switch to a default theme
   • Rename your active theme folder
   • WordPress will automatically switch to a default theme
3. Increase PHP memory limit
   Add this line to wp-config.php:define('WP_MEMORY_LIMIT', '256M');

2. Error Establishing a Database Connection

What It Means

WordPress cannot connect to your database.

Causes

• Incorrect database credentials
• Corrupted database
• Hosting server issue

Fix Steps

1. Check database credentials in wp-config.php
   • DB_NAME
   • DB_USER
   • DB_PASSWORD

   Add this temporarily to wp-config.php:define('WP_ALLOW_REPAIR', true); Visit: yoursite.com/wp-admin/maint/repair.php
3. Contact hosting support if the server is down

3. 404 Errors on Posts or Pages
