Common WordPress Errors

Solution:
- Rename the file .htaccess and regenerate it via Settings > Permalink.

White Screen of Death
This white screen can completely block access to your site. Common causes include:
- Conflicts between plugins or themes

- Incorrect code in theme or plugin
Solution:
- Activate a default theme like Twenty TwentyThree.
- Deactivate all plugins via FTP or from the database.
- Check the file error_log to identify the problem.
Error 404 (Page Not Found)
404 errors are annoying for the user and harmful to the SEO of your e-commerce. They occur when a page does not exist or the DNS is not configured correctly.
Solution:
- Please make sure your permalinks are correct.
- Make sure DNS is propagated correctly.
- Use a plugin like Redirection to fix broken links.
Database Connection Problems
If WordPress fails to connect to the database, your e-commerce site will be offline. Causes include:

- Database corrupted.
Solution:
- Verify the credentials in the file wp-config.php.

Plugin and conflict management
E-commerce sites often use numerous plugins, increasing the risk of conflicts. Here's how to manage them:
- Keep only essential plugins active.
- Update all plugins regularly.

A slow website can hurt your user experience and sales. Improve your ecommerce speed with these steps:
- Use a caching plugin like WP Rocket.

PHP Compatibility Issues
WordPress requires an up-to-date version of PHP to run properly. Make sure your hosting supports the latest stable version.
Solution:
- Update your PHP version from your hosting dashboard.

Security on WordPress
Hackers are a constant threat to e-commerce. Protect your site with these strategies:

Backup and Restore: Why They Are Crucial
An effective backup system is essential to avoid data loss. Use tools like Updraft Plus or Backup Buddy to create automatic backups.
