If you've encountered the issue of a shortcode created within your Wordpress plugin not displaying the expected content on your website, you're not alone. This problem can stem from several causes, ranging from simple typos to more complex compatibility issues or plugin conflicts. In this article, we'll discuss several common reasons why this might happen and offer solutions to help you resolve the issue.

Check the Shortcode Syntax

The first step should be to verify that you've correctly registered the shortcode in your plugin. WordPress uses the add_shortcode() function, where the first parameter is the shortcode name and the second is the name of the function to be called when the shortcode is used. Make sure that the syntax of your shortcode is correct and free of any typos.

function my_custom_shortcode() {
    return 'Content of my shortcode';
}
add_shortcode('my_shortcode', 'my_custom_shortcode');

Check for Conflicts with Other Plugins

Another step is to check for conflicts with other plugins. Some plugins may override or affect the functionality of your shortcode. Try temporarily deactivating other plugins and see if the issue resolves.

Verify the WordPress Theme

Sometimes the problem may be caused by specific settings or limitations in your WordPress theme. Try switching to a default WordPress theme such as Twenty Twenty-One and check if the shortcode content displays correctly.

Utilize WordPress Filters and Actions

If your shortcode requires specific modifications or content manipulation, ensure that you're correctly using WordPress filters and actions. Improper use of these hooks can result in the content not being processed or displayed correctly.

Debugging and Troubleshooting

WordPress offers tools and methods for debugging that can help you identify the problem. By enabling debugging in the wp-config.php file, you can display error messages that will help you pinpoint where exactly the issue lies.

define('WP_DEBUG', true);

Troubleshooting issues with shortcode in a WordPress plugin can sometimes be complex, but with the right approach and understanding of the basic principles, you can successfully resolve the problem. Remember that careful code review, testing in an isolated environment, and leveraging the WordPress community for advice and support can be invaluable.
