Optimising a WordPress Site Bloated by Too Many Plugins, Buggy Code, and Security Vulnerabilities

Maintaining a WordPress site can become challenging as it grows in complexity, particularly if too many plugins are installed or buggy code is slowing down performance.

If your website is feeling sluggish or facing loading issues, it’s time to optimise and streamline its performance. A bloated WordPress site affects user experience, impacts search engine rankings, and can also introduce security vulnerabilities.

At WordPress Website Support, we specialise in the development, support, and maintenance of WordPress websites. We can assist you with cleaning up, optimising, and enhancing your site’s speed and security.

However, if you have some technical expertise and would like to conduct some of this work yourself, here is a guide to help you optimise your website for both performance and security.

1. Audit Installed Plugins

Plugins extend WordPress functionality, but too many can bloat your site, slow down performance, and increase security risks.

• Remove Unnecessary Plugins: Review your active plugins. Do you really need all of them? Eliminate any that are redundant or underperforming. Deactivating or removing plugins you don’t need reduces both security risks and performance bottlenecks. It is easy to uninstall inactive plugins, but plugins that are installed and if you are unsure of whether the plugin is used or not, may require some trial and error which can be time consuming.
• Combine Functions Where Possible: A single premium plugin can often replace several free plugins, combining functionality into a more efficient tool.
• Look for Lightweight Alternatives: Some plugins are unnecessarily heavy. Research lightweight alternatives that perform the same functions but with a smaller codebase and fewer vulnerabilities.
• Regularly Update Plugins: Keeping plugins up to date not only improves performance but also ensures security patches are applied, reducing vulnerabilities.

2. Identify and Fix Buggy Code

Buggy code can significantly slow down your WordPress site and introduce security issues. Identifying and fixing these problems is crucial.

• Error Logs: Enable WP_DEBUG mode in WordPress to track down errors and warnings that could indicate buggy or insecure code.
• Manual Code Review: If your site relies on custom code or a custom theme, review it for inefficiencies, unused scripts, or outdated practices. Clean up unused code, as it can both slow down your site and expose security risks.
• Use Debugging Plugins: Tools like Query Monitor help track down problematic code or database queries, making it easier to resolve performance issues and potential security vulnerabilities.

3. Optimise and Secure Database Performance

WordPress heavily relies on its database, which can become bloated over time, slowing down your site and increasing security risks. Regular database optimisation helps maintain performance, website speed and security.

• Clean Up Revisions and Drafts: Regularly clean up post revisions and drafts that accumulate in the database using a plugin like WP-Optimize.
• Delete Unused Data: Delete spam comments, expired transients, and unused meta fields to reduce unnecessary database load and minimise potential attack surfaces.
• Database Optimisation Tools: Use plugins like Advanced Database Cleaner or WP-DBManager to optimise your database safely and ensure it runs efficiently.
• Backup Your Database Regularly: Always back up your database to safeguard against data loss due to hacking or server failures.

4. Optimise Front-End Performance

A bloated front-end with too many scripts and styles loading simultaneously will drastically reduce performance and can expose security vulnerabilities.

• Minimise CSS and JavaScript Files: Use plugins like Autoptimize to minify and combine CSS and JavaScript files. This reduces the number of HTTP requests and file sizes, speeding up page load times while eliminating potential script vulnerabilities.
• Lazy Load Images and Videos: Lazy loading media ensures images and videos only load when necessary, reducing initial load times and protecting your site from unnecessary bandwidth strain.
• Security Headers: Implement security headers like Content-Security-Policy to protect your site from cross-site scripting (XSS) and other attacks while improving performance.
• Utilise Caching: Leverage caching plugins such as WP Rocket or W3 Total Cache. Caching reduces the load on your server, improves speed, and reduces the risk of DDoS attacks by minimising server requests.

5. Consider Using a CDN

A Content Delivery Network (CDN) stores copies of your site on servers across the globe, reducing load times for users and providing a layer of security.

• Choose a Reliable CDN Provider: A CDN provider like Cloudflare or KeyCDN improves performance and offers security features such as DDoS protection and Web Application Firewalls (WAF).
• Optimise Images Before Uploading: Always compress images before uploading them to WordPress. Use tools like ShortPixel or Smush to automatically compress images, speeding up your site and reducing vulnerabilities related to oversized media files.

6. Regular Maintenance and Monitoring

WordPress sites need regular maintenance to stay fast and secure. Outdated plugins, themes, and WordPress core files are common targets for hackers.

• Update Plugins, Themes, and Core Files: Keeping everything up to date is crucial for both performance and security. Newer versions often include performance optimisations and security patches.
• Install Security Plugins: Use security plugins like Wordfence or Sucuri Security, which offer firewall protection, malware scanning, and login protection.
• Monitor Site Performance and Security: Tools like Google PageSpeed Insights or GTmetrix can help you regularly monitor your site’s performance, while security scanners like WPScan will alert you to potential vulnerabilities.

7. Strengthen Login Security

Login pages are a common target for hackers, and protecting them is essential.

• Enable Two-Factor Authentication (2FA): Adding two-factor authentication makes it much harder for attackers to gain access, even if they obtain your password.
• Limit Login Attempts: Use plugins that limit the number of failed login attempts to protect your site against brute-force attacks.
• Use Strong Passwords: Ensure that all admin and user accounts use strong, unique passwords to reduce the risk of unauthorised access.
