1. Not Keeping WordPress and Plugins Up-to-Date

One of the most critical mistakes a WordPress developer can make is not keeping their WordPress installation and plugins up-to-date. Not only do updates often include important security patches, but they also improve the functionality of your website and fix bugs.

To avoid this mistake, it’s essential to set up automatic updates for your WordPress installation and plugins, or to make sure to check for updates regularly. You can also consider using a plugin that sends you notifications when updates are available.


2. Not Using Child Themes

When customizing a WordPress theme, it’s common to make changes directly to the theme’s files. However, this can lead to problems if the theme is updated later on.

To avoid this mistake, it’s essential to use a child theme when customizing your website. A child theme allows you to make changes to your website’s design without modifying the parent theme’s files. This way, you can update the parent theme without losing your customizations.

3. Not Optimizing Images

Optimizing images can significantly improve your website’s load time. However, it’s easy to forget to optimize images before uploading them to your website.

To avoid this mistake, it’s essential to optimize images before uploading them to your website. There are several image optimization plugins available that can help you reduce the

size of your images without sacrificing quality. Additionally, make sure to use images with appropriate dimensions and format that are optimized for web and avoid using images that are too large.

4. Not Securing Your Website

WordPress websites are often targeted by hackers due to their popularity. If a website is not properly secured, it can lead to data breaches and other security issues.

To avoid this mistake, it’s essential to secure your website by keeping your WordPress installation, themes and plugins up-to-date, as well as by using a strong and unique login password. Additionally, you should use security plugins that can help you prevent hacking attempts and malware attacks, and regularly monitor your website for any suspicious activity.

5. Not Backing Up Your Website

Not having a proper backup plan in place can be disastrous in case something goes wrong with your website. Losing your website’s data can be a frustrating and time-consuming experience.

To avoid this mistake, it’s essential to backup your website regularly, and store the backup files in a safe place. You can use plugins or external services to schedule automatic backups, or you can manually download your website’s data. It’s also recommended to test your backups to make sure they can be restored.


These are some of the most common mistakes that WordPress developers make. By keeping these in mind and taking steps to avoid them, you can ensure that your website is functional, secure, and well-maintained. Remember to always backup your website, use child themes, optimize images, keep your WordPress and plugins up-to-date, and use security plugins. It’s important to regularly review and monitor your website to make sure it runs smoothly.
