Common WordPress Development Issues and How to Deal with Them

Wordpress Development Issues

WordPress is indeed a powerful tool for making cutting-edge websites. Millions of websites across the globe use it because of its intuitive design, large plugin ecosystem, and plenty of personalization choices. However, it also has certain limitations that affect site functioning. In this article, we will explore several WordPress development issues that are often encountered and provide you with practical solutions.

WordPress has grown into a world-leading platform for website building in recent years. With a large user base, it is the most prominent open-source content management system (CMS). Since its launch in 2003, WordPress has evolved into a powerful CMS that accounts for almost 64% of the global market.

Due to WordPress’s growing popularity, many businesses are drawn to using it for a variety of websites, from personal blogs to e-commerce sites.

However, building a WordPress site isn’t without difficulties. Keeping up with WordPress’s ever-changing features, security improvements, and best practices constantly challenges developers. Another major obstacle is optimizing the performance of WordPress websites. Hence, developers should always look for ways to optimize their WordPress sites and deal with these common concerns. 

So, let’s explore some of the common WordPress development issues and learn some effective ways to overcome them.

Most Common WordPress Development Issues

Plugin Compatability Issues

A plugin conflict is the incompatibility of two or more plugins’ features. It can lead to website crashes. Notably, these conflicts between plugins can happen if they cannot sync with the current WordPress version or if they have incompatible code.

Some signs of plugin incompatibilities include malfunctioning functionality or the 500 Internal Server Error. Resultantly, these problems can cause the site to malfunction or even damage the company’s reputation.


  • Ensure your plugins are compatible with the recent WordPress releases by regularly upgrading them to the newest versions.
  • Test the plugin you are installing or updating in a staging environment to ensure it is compatible with all other plugins and the WordPress core.
  • Deactivating plugins one by one could help you see which ones are at odds.
  • If you’re having problems with plugin conflicts, try using a debugging tool like WP_DEBUG. 

Theme Customization Challenges

Due to the limited flexibility of some themes, customizing WordPress themes to fit particular needs may be challenging. Themes with rigid frameworks or limited modification options cause this problem.

Developers trying to modify the website’s look to fit project specifications can find this frustrating. In the end, this can make clients and visitors unhappy.


  • Prefer themes that are easy to personalize in terms of layout, font, and color schemes.
  • Create a child theme to make changes to a theme without altering the main files of the parent theme.
  • Use the Customizer, which is already a part of WordPress, to see how your changes will look before you commit them.
  • Use the block-based editor in Gutenberg to make your WordPress theme seem more interactive. 

Security Vulnerabilities

Because of its popularity, WordPress is often targeted by cybercriminals. Website integrity could be affected due to website security vulnerabilities caused by outdated software or insecure plugins or themes.

Consequences such as data theft, significant financial losses, website damage, and loss of client confidence could arise from security breaches. Moreover, the site and the brand’s reputation may take a hit when malicious actions like phishing or virus distribution happen.

A WordPress site can pose vulnerabilities due to:

  • Plugins that are either outdated or poorly coded.
  • Insecure login credentials.
  • Not using security protocols such as HTTPS or two-factor authentication.
  • Uploads of files without proper security.


  • Regularly update WordPress plugins, core, or themes to fix security issues.
  • Ensure strict guidelines for passwords, mandating the use of complicated combinations of letters, numbers, and special characters.
  • Use a trusted security plugin such as Wordfence to protect your site from malicious activity.
  • To make user logins even more secure, use two-factor authentication.
  • Limit who may access crucial documents and their associated folders by setting the correct file permissions.

Performance Optimization Issues

Websites that take a longer time to load adversely affect search engine rankings and make users unhappy. Problems with WordPress performance, such as poorly optimized pictures or an excess of HTTP requests, might cause a drop in traffic.

Most users will not stay on a slow-loading website. Loss of opportunity is another significant consequence of poor performance.


  • Pick a streamlined theme like Astra instead of one with too many features.
  • Combining CSS and JavaScript files may reduce the number of HTTP requests.
  • Launch a content delivery network (CDN) that distributes website content over servers worldwide.
  • Create static HTML copies of dynamic content by installing caching plugins.

White Screen of Death, or WSOD

A frustrating problem with WordPress is the White Screen of Death (WSOD), which causes the whole website to show a blank white screen without the error code. This makes it difficult to identify the cause. Several potential causes of WSOD exist, such as PHP issues, corrupted files, or plugin/theme incompatibilities.

If WSOD occurs, users cannot access certain pages or the website, which can significantly decrease site traffic and ROI. If the problem lasts, it damages the business’s reputation.


  • Turn on debugging mode in WordPress to help you figure out what’s causing WSOD.
  • If WSOD happens after you have installed any plugins or themes, disable them.
  • WSOD can occur when PHP memory is insufficient. To improve the PHP memory limit, modify the wp-config.php or php.ini files.
  • Look for syntax mistakes in the theme or plugin files that are causing WSOD. To fix syntax mistakes, use a code editor with error-checking features.
  • Find server-side issues that might be causing WSOD by accessing the server error logs using FTP or cPanel.

Database Issues

Database challenges can slow down WordPress site performance. Issues like this often arise due to database proliferation or fragmented tables.

Website outages or difficulty connecting to databases are common signs of database issues that negatively impact the user experience. Slow database queries increase response times, which in turn affects user engagement. If these database issues cause data loss, the integrity of the WordPress site might be compromised.


  • Remove unnecessary information from the WordPress database regularly. Automate database cleanups using plugins like WP-Optimize or WP-Sweep.
  • Optimizing database tables after deleting revisions can improve query speed. Use a plugin like WP-DBManager to optimize tables after deleting revisions.
  • Set up periodic maintenance operations to automate database optimization. Backup your database regularly using plugins or scripts run on the server.
  • Using applications like New Relic, monitor key performance indicators for your database. Examine the time it takes for queries to run and make adjustments to speed up the site throughout its lifespan.
  • Get the most out of your database by fine-tuning its setup settings. To improve database speed, you may modify MySQL or MariaDB settings based on your server’s resources. It includes query cache size, InnoDB buffer pool size, and max_connections.


Tackling these WordPress concerns is important to have your website functioning seamlessly. Though minor and common, these issues have the potential to adversely affect your site’s performance, SEO, and lead-generating efforts. You can hire WordPress developers if you are not familiar with the development process. 

So, leverage the above-mentioned solutions for your distinct WordPress development issues, along with expert solutions, to help you identify the problem quickly and get your website running smoothly.
