Introduction
WordPress is one of the most popular website platforms in the world. Millions of websites run on it every day. However, even the best platforms can sometimes show errors.
Many WordPress users experience issues such as login problems, server errors, or broken pages. The good news is that most of these problems are very common and easy to fix.
In this guide, we’ll look at the most frequently reported WordPress errors and how you can solve them quickly.

This error appears when WordPress cannot communicate with its database.
Common Causes

Check the database details inside the wp-config.php file. Make sure the following values are correct:

Sometimes your posts or pages suddenly start showing 404 errors, even though they exist.
How to Fix It

7. WordPress Not Sending Emails
WordPress sometimes fails to send emails such as password reset messages or contact form notifications.

How to Fix It
Use an SMTP plugin and connect your website to a reliable email service like Gmail or another mail server.
This improves email delivery and reliability.

A redirect loop happens when your website continuously redirects visitors between URLs.
This usually results in the browser message:

Check your WordPress site URL settings and make sure there are no conflicting redirects in plugins or server configuration.
Clearing cache and cookies can also help.
