Display All Posts on Category Page in WordPress - Easy Guide

Customizing Posts Per Page in WordPress
A common limitation within the standard WordPress installation is the global setting for the number of posts displayed on each page. This lacks the flexibility to tailor post counts for specific sections or individual pages.
Fortunately, a plugin developed by Matt Read provides a straightforward solution to this issue.
Plugin Installation
The first step involves obtaining the plugin from the developer’s website and installing it within your WordPress environment.
Installation is achieved by unzipping the plugin file and uploading it to the BLOGROOT/wp-content/plugins/ directory.
Note: The original download location appears to be unavailable. A mirror copy is provided for convenience.

Plugin Configuration
After installation, activate the CQS plugin through the Plugins page in your WordPress control panel.
Navigate to Options / CQS to access the plugin’s configuration screen.
To customize the number of posts displayed within categories, select "is_category" from the Query dropdown menu.
Set the Show condition to -1 to apply the changes to all posts within those categories.
Click the Add button to save the configuration.
Further Customization
Additional conditions can be added to refine post display on specific pages.
For example, you can configure the homepage to display only 5 posts per page, creating a less cluttered presentation.
This level of control allows for a more tailored user experience across your WordPress site.
