Hi @garrigan ,

Those PHP messages are intentional debug logging in the prevent_llms_txt_redirect function. They’re designed to help troubleshoot URL redirect issues, but they
only appear when WP_DEBUG is enabled.

To remove these messages, you have two options:

1. Disable debug mode (recommended for production):
   • In your wp-config.php file, change:
     define('WP_DEBUG', true); to define('WP_DEBUG', false);
2. Remove the debug code from the plugin:
   • Edit the plugin file and remove lines 259-261 and 266-268 (the error_log statements)
   The function is working properly – these logs just confirm it’s preventing WordPress from incorrectly redirecting llms.txt URLs with trailing slashes. Thanks for testing!

Hi @garrigan ,

Thank you for those detailed screenshots! I can see exactly what’s happening now.

I found the issue – there’s a bug in our v1.0.6 regex pattern that doesn’t handle all URL formats correctly.

Here’s what you need to do:

1. Download the updated plugin (we’re releasing v1.0.7 with the fix)
2. Or apply this quick fix manually: In your ai-content-guide.php file, find this line (around line 260):
   if (preg_match(‘/\/llms(-full)?.txt\/?$/’, $requested_url)) { Replace it with:
   if (preg_match(‘/(?:^|\/?)llms(-full)?.txt\/?$/’, $requested_url)) {
3. Clear all caches and test again What was wrong: The original regex required a forward slash before “llms” but WordPress sometimes passes URLs without it, causing the redirect prevention to fail. Your analysis was perfect – you correctly identified that return false; prevents the redirect. The issue was that our pattern wasn’t matching your URLs properly. The fix handles URLs in all these formats:

• yoursite.com/llms.txt
• yoursite.com/llms.txt/
• llms.txt (relative)
• /llms.txt (absolute) Let me know if this resolves the issue!

Thank you for reporting this issue with the trailing slash redirects on your llms.txt files. I’ve identified and fixed the root cause.

Problem:
WordPress was automatically adding trailing slashes to your llms.txt and llms-full.txt URLs through its canonical redirect functionality, causing unwanted 301 redirects
before our plugin could handle the requests.

Solution:
I’ve updated the plugin code to prevent WordPress from redirecting these specific URLs. The fix adds a filter that intercepts the canonical redirect for llms.txt files and
prevents the automatic trailing slash addition.

What was changed:

• Added redirect_canonical filter to prevent WordPress from redirecting llms.txt URLs
• Added prevent_llms_txt_redirect() method to handle the redirect prevention logic Expected behavior after update:
• https://staging.garriganenterprises.com/llms.txt → 200 OK (no redirect)
• https://staging.garriganenterprises.com/llms-full.txt → 200 OK (no redirect) This fix will be included in the next plugin update. The issue was not related to your NGINX configuration – it was WordPress’s default behavior that needed to be overridden.
  
  Please test after the update and let me know if you encounter any further issues.
