This Is What Causes Your WordPress Custom Taxonomy Template to Not Display on the Archive Page
If you've created a custom taxonomy in WordPress and built a custom template for it, you may have encountered an issue where that template doesn't display on the archive page for that taxonomy. This can be a frustrating problem, and there are a few potential causes behind it.
In this article, we'll dive into the most common reasons why your custom taxonomy template might not be showing up, and provide step-by-step solutions to get it working correctly. By the end, you'll have a better understanding of how custom taxonomies work in WordPress and be able to troubleshoot this problem on your own site.
The Importance of Custom Taxonomies in WordPress
Before we get into the specifics of the problem, let's quickly review why custom taxonomies are so valuable in WordPress. Taxonomies in WordPress refer to the classification system used to organize and group content on your site.
The two default taxonomies in WordPress are:
- Categories: Used to group posts into broader topics or themes.
- Tags: Used to add more granular keywords or labels to individual posts.
While these default taxonomies are useful, many WordPress sites require more advanced classification systems to properly organize their content. That's where custom taxonomies come in.
Custom taxonomies allow you to create your own classification terms and hierarchies, tailored specifically to the needs of your website. This gives you much more flexibility in how you structure and present your content to users.
Some examples of custom taxonomies include:
- Products: If you run an ecommerce site, you might create custom taxonomies for product type, brand, material, etc.
- Destinations: For a travel blog, you could have custom taxonomies for continent, country, city, etc.
- Recipes: A food blog might use custom taxonomies for cuisine type, dietary restrictions, main ingredient, etc.
The key benefit of custom taxonomies is that they enable you to create a content organization system that aligns perfectly with your specific business or website needs. This makes it much easier for users to navigate and discover the content they're looking for.
Why Isn't My Custom Taxonomy Template Showing Up?
Now that we've covered the importance of custom taxonomies, let's dive into the main problem at hand – why isn't your custom taxonomy template displaying on the archive page?
There are a few common reasons this can happen:
-
Incorrect Template Filename: WordPress has specific naming conventions for template files that it looks for. If your custom taxonomy template file doesn't follow these conventions, WordPress won't be able to locate and load it properly.
-
Incorrect Template Hierarchy: WordPress has a specific hierarchy it follows when determining which template file to use for a given page. If your custom taxonomy template isn't placed correctly in this hierarchy, it may not be selected.
-
Caching Issues: If you have any caching plugins or server-side caching enabled on your WordPress site, that could be preventing the custom taxonomy template from being properly refreshed and displayed.
-
Disabled Taxonomy Archive Pages: In some cases, WordPress may have the custom taxonomy archive pages disabled by default, preventing the template from being used.
Let's take a closer look at each of these potential issues and how to resolve them.
Incorrect Template Filename
WordPress has specific naming conventions for template files that it will recognize and use. For custom taxonomy templates, the required filename format is:
taxonomy-{taxonomy-name}.php
Where {taxonomy-name}
is the slug of your custom taxonomy.
For example, if you have a custom taxonomy called "product_type", the correct template filename would be taxonomy-product_type.php
.
Make sure the filename of your custom taxonomy template matches this convention exactly. If it doesn't, WordPress won't be able to locate and load the template properly.
Incorrect Template Hierarchy
WordPress also follows a specific hierarchy when determining which template file to use for a given page. For custom taxonomy archive pages, the hierarchy is:
taxonomy-{taxonomy-name}.php
taxonomy.php
archive.php
index.php
This means that WordPress will first try to load the template file named taxonomy-{taxonomy-name}.php
, then fall back to taxonomy.php
, then archive.php
, and finally index.php
if none of the more specific templates are found.
Ensure that your custom taxonomy template file is located in the correct hierarchy. It should be in the root directory of your active WordPress theme, not in a subdirectory. If the file is not in the right place, WordPress won't be able to find and use it.
Caching Issues
If you have any caching plugins or server-side caching enabled on your WordPress site, that could be preventing your custom taxonomy template from being properly refreshed and displayed.
Caching can sometimes "hold onto" an older version of your template, even after you've made changes to it. This can lead to the template not showing up as expected on the archive page.
To troubleshoot this, try clearing your site's cache completely, either by disabling the caching plugin or manually clearing the cache through your hosting provider's control panel. Then, refresh the custom taxonomy archive page and see if the template now displays correctly.

Disabled Taxonomy Archive Pages
In some cases, WordPress may have the custom taxonomy archive pages disabled by default, preventing the template from being used.
To check if this is the case, go to your WordPress admin dashboard and navigate to Settings > Permalinks. Scroll down to the "Custom Structure" field and make sure the following structure is in place:
/%taxonomy%/%term%/
This tells WordPress to enable the archive pages for your custom taxonomies. If the field is blank or using a different structure, update it to the one above and save the changes.
After making this update, try refreshing the custom taxonomy archive page again – your template should now display correctly.
Putting It All Together: Steps to Fix the Issue
Now that we've covered the potential causes, let's summarize the steps you can take to troubleshoot and fix the issue of your custom taxonomy template not displaying on the archive page:
-
Check the Template Filename: Ensure the filename of your custom taxonomy template follows the correct convention: taxonomy-{taxonomy-name}.php
.
-
Verify the Template Hierarchy: Make sure the custom taxonomy template file is located in the root directory of your active WordPress theme, not in a subdirectory.
-
Clear the Site's Cache: If you have any caching plugins or server-side caching enabled, try clearing the cache completely and then refresh the custom taxonomy archive page.
-
Enable Taxonomy Archive Pages: Go to your WordPress admin dashboard, navigate to Settings > Permalinks, and make sure the "Custom Structure" field is set to /%taxonomy%/%term%/
.
By following these steps, you should be able to identify and resolve the issue causing your custom taxonomy template to not display on the archive page. Remember, the key is ensuring that WordPress can properly locate and load the template file.
If you're still having trouble after trying these troubleshooting steps, you may want to consult the WordPress documentation or reach out to the WordPress support community for additional assistance.
