In this in-depth guide, I‘ll leverage my expertise to explain what‘s causing this error, and walk through how to fully fix it step-by-step. By properly allowing Googlebot access, we can maximize your site‘s chances of ranking in search results.

Why Googlebot Needs to Access CSS and JS
Before diving into solutions, let‘s discuss why allowing Googlebot access to CSS and JavaScript files matters for SEO.
Google ranks websites based on how well it can understand and render their content. Cascading Style Sheets (CSS) and JavaScript (JS) files contain key information on how your pages are structured and presented.
If Googlebot can‘t read CSS/JS, it may improperly index pages or undervalue their relevance. I‘ve seen sites plummet in rankings after encountering blocked resources.
That‘s why properly optimizing your robots.txt file is so important – it removes access barriers and allows comprehensive Googlebot crawling.
Identifying Blocked Resources
The first step is finding out which CSS/JS files Googlebot is blocked from reaching. The most common causes are overzealous security plugins or hosting restrictions.
Here are two easy ways to identify blocked resources:
Search Console Fetch as Google Tool
Go to Crawl > Fetch as Google. Fetch and render pages – compare to user view. See differences? Those are blocked files.
Blocked Resources Section
Navigate to Index > Blocked Resources. This lists URLs Googlebot encountered access restrictions on.
Review both reports to pinpoint any problematic CSS/JS files. Often these will come from plugins like security suites or the theme itself.
Editing Your Robots.txt File
Now that we know which resources are blocked, we can remove the restrictions preventing Googlebot access.
The main way to control Googlebot access is via the robots.txt file in your root directory. You have two options for editing:
Via FTP
Use an FTP client to connect and directly edit robots.txt in a text editor. This gives you full control.
Yoast SEO File Editor
If you have Yoast SEO installed, navigate to SEO > Tools > File Editor. This lets you edit within WordPress admin.
Open your robots.txt file and look for any Disallow rules blocking wp-content paths or wp-includes. Delete those lines to whitelist access.
For example:
# Allow access to CSS files
Allow: /wp-content/themes/mytheme/css/
# Allow access to JS libraries
Allow: /wp-includes/js/Save your changes and re-fetch pages as Google to confirm everything is now accessible!
Additional Troubleshooting Tips
In some tricky cases, you may still see blocked resources even after updating robots.txt. Try these tips:
-
Temporarily deactivate plugins – systematically disable plugins one-by-one to isolate conflicts.
-
Ask your host for access – some impose hidden restrictions beyond robots.txt.
-
Resubmit XML sitemap – fetch/render as Google to re-crawl.
-
Monitor blocked resources – occasionally recheck as you update plugins/theme.
Take a proactive approach to prevent future conflicts. Keep your WordPress SEO plugins up to date and avoid unnecessary access restrictions.
