Common WordPress Security Mistakes and How to Avoid Them

WordPress dominates the web as the leading content management system (CMS), powering over 40% of all websites in the world. Its widespread popularity stems from its user-friendly interface and extensive plugin library, making it a favored option for individuals and businesses.

However, safeguarding the security of your WordPress website should be a top priority. With ever-evolving cyber threats, neglecting even basic security practices can expose your website to potential attacks.

Here are five common WordPress security errors and practical solutions to preventing them.

Weak Passwords

One of the most common security mistakes WordPress users make is using weak passwords. Many people tend to use common passwords or ones that are easy to remember, such as “123456” or “password.” These passwords are extremely vulnerable to brute-force attacks, where hackers systematically attempt various combinations until they crack the password.


Create a strong password by using a combination of upper and lower case letters, numbers, and special characters. Avoid using common words or personal information that can be easily guessed. Password generators, such as LastPass or KeePass, can help you generate complex and unique passwords for each of your online accounts, including your WordPress website.

Consider implementing two-factor authentication (2FA) for an extra layer of security. 2FA requires users to provide an additional verification step, typically a code generated by a mobile app or sent via SMS, along with their password. This adds an extra barrier for hackers trying to gain unauthorized access to your website.

Another helpful solution is using a password manager like RoboForm, which securely stores and remembers your passwords. Password managers not only generate strong passwords for you but also store them in an encrypted format, making it convenient and safe to manage your login credentials for various websites, including your WordPress admin panel.

Failure to Update Themes, and Plugins

WordPress regularly releases updates that address security vulnerabilities, improve performance, and add new features. Ignoring these updates can leave your website exposed to known vulnerabilities that hackers can exploit. Additionally, outdated themes and plugins can have security flaws that are fixed in newer versions.


Regularly update your WordPress, themes, and plugins to the latest versions. Enable automatic updates whenever possible, but make sure to back up your website before implementing any updates.

When it comes to themes and plugins, it’s crucial to be mindful of where you source them from. Here are some tips:

  • Official WordPress Repository: The official WordPress repository is a trusted source for free themes and plugins. It offers a wide range of options, and all themes and plugins go through a review process before being made available.
  • Reputable Theme and Plugin Marketplaces: There are several reputable marketplaces where you can find both free and paid themes and plugins. Examples include ThemeForest, CodeCanyon, and Elegant Themes. These marketplaces offer a wide selection of professionally designed themes and plugins from trusted developers.
  • Developer Websites: Many theme and plugin developers offer their products directly through their websites. This can be a good option if you have specific requirements or prefer to support a particular developer.

Using Unsecure or Outdated Themes and Plugins

Using unsecure or outdated themes and plugins is another common security mistake. Free or nulled themes and plugins downloaded from unreliable sources often contain malicious code that can compromise your website’s security. Outdated themes and plugins may have unpatched vulnerabilities that hackers can exploit.


Stick to reputable sources such as the official WordPress repository, reputable theme and plugin marketplaces, or trusted developers’ websites.  But before that:

  • Read User Reviews and Ratings: Before installing a theme or plugin, check the user reviews and ratings. This feedback provides insights into the experiences of other users. Look for high ratings and positive reviews, as these indicate that the theme or plugin has been well-received by the community.
  • Verify Developer Reputation: Research the reputation of the theme or plugin developer. Visit their website, review their portfolio, and check if they have a history of producing secure and well-maintained products. Look for developers who actively update their themes and plugins, as this demonstrates their commitment to security and functionality.
  • Check for Regular Updates: Ensure that the theme or plugin you choose is actively maintained and regularly updated. Regular updates are a sign that the developer is actively addressing security vulnerabilities, adding new features, and improving compatibility with the latest version of WordPress. Avoid themes or plugins that have not been updated for a long time, as they may pose a higher security risk.
  • Consider Premium Themes and Plugins: While free themes and plugins can be a good starting point, premium options often provide better security and support. Premium themes and plugins are usually developed by professional teams with dedicated support and frequent updates. Investing in a premium theme or plugin can offer added peace of mind and additional features tailored to your specific needs.
  • Perform Security Scans: Use security plugins or online scanning tools to check the integrity of themes and plugins before installation. These tools can help identify any malicious code or vulnerabilities present in the files. Additionally, security plugins can provide ongoing protection by monitoring your website for potential security threats.

Neglecting File Permissions and Directory Listings

One common mistake that many WordPress users make is neglecting to properly manage file permissions and directory listings on their websites. File permissions and directory listings play a crucial role in website security and can have significant implications if not handled correctly.


File permissions in WordPress control access, modification, and execution of files. Setting overly permissive permissions can leave websites vulnerable to hacking and malicious code injection.

Properly configuring permissions, such as 755 for directories and 644 for files, ensures necessary access while maintaining security.

Disabling directory listings is crucial to prevent unauthorized access to sensitive data. This can be done through modifications in the .htaccess file or using security plugins. By addressing these issues, WordPress users can enhance security and protect their websites from potential risks.

Lack of Website Backups

Not having regular website backups is a grave mistake that can result in significant data loss or downtime in the event of a security breach or website malfunction. Without a backup, recovering your website and its content can be challenging, time-consuming, and sometimes impossible.


Set up automatic backups of your WordPress website to a remote location, such as cloud storage or an external server. Ensure that your backup solution includes both your database and files. Here’s the basics on how you can establish an effective backup strategy:

  • Choose a Reliable Backup Solution: There are numerous backup plugins and services available for WordPress. Opt for a reputable and well-reviewed backup solution that suits your needs. Some popular backup plugins include UpdraftPlus, BackupBuddy, and VaultPress.
  • Schedule Regular Automated Backups: Set up automated backups on a regular basis to ensure that your website is consistently backed up. Automating the process reduces the risk of forgetting to perform manual backups and ensures that your data is always protected.
  • Store Backups Off-Site: This protects your backups from being compromised if your server experiences a security breach or a physical failure. Cloud storage services like Dropbox, Google Drive, or Amazon S3 are popular choices for securely storing backups off-site.
  • Consider an Off-Site Backup Service: If managing backups yourself seems overwhelming, consider using a specialized off-site backup service. These services offer automated backups, secure storage, and easy restoration options.

Final Thoughts Stay proactive, implement robust security practices, and consistently assess and enhance the security measures for your WordPress website. Safeguarding your website will not only protect your data and reputation but also provide peace of mind so that you can navigate the digital landscape with confidence.
