The script resource is behind a redirect, which is disallowed

Hello. I am currently having an issue with embedding Discourse on WordPress website.

I have set the following:

Allowed Host:

But I get the following error response in Chrome Console:

The script resource is behind a redirect, which is disallowed.
Failed to load resource: net::ERR_UNSAFE_REDIRECT service-workers.js

In Firefox I get this text displayed:


The software powering this discussion forum encountered an unexpected problem. We apologize for the inconvenience.

Detailed information about the error was logged, and an automatic notification generated. We’ll take a look at it.

The Iframe is loaded but it only displays Loading Comments. I am doing the loading of the scripts via AJAX response. Perhaps that might be the issue?

Any help would be greatly appreciated.

I bet it is.

Just load it in the standard way, the script tag.

<div id='discourse-comments'></div>";
    		<script type='text/javascript'>
    			  DiscourseEmbed = { discourseUrl: '',
    								 discourseEmbedUrl: '' };

    			  (function() {
    				var d = document.createElement('script'); d.type = 'text/javascript'; d.async = true;
    				d.src = DiscourseEmbed.discourseUrl + 'javascripts/embed.js';
    				(document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(d);

I have added the code above in the PHP file (that is not dynamically generated by AJAX), but I get the following error in Chrome:

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

Just in case: you are taking the embedding route because you don’t have access to the installation of plugins in your WordPress, right?

Hmm, To Serve Man, with Software is loading just fine for me.

Can you update Discourse to latest? Can you share the URL where the comments are embedded ?


we’re actually trying to load this a wordpress site (currently behind a temp maintenance page) and this forum. everything is updated to the latest.

Why not use the official Wordpress plugin?

we’re not trying to have every post create a new topic. we’re just trying to embed one particular topic or category into a page.

I could be wrong (please correct me if I am @Simon_Cossar) - but with the official plugin you can choose selectively whether to create a Discourse topic or not.


Right, but we already have an existing page and want to insert a specific category or existing thread into it, if that makes sense. we’re not going to have wordpress create new posts/pages and have it create a new thread.

i’ll dig in a bit deeper on the plugin and see if we can configure it to do what we want. :slight_smile:

The WordPress plugin has an option to link WordPress posts to Discourse topics without publishing the post from WordPress to Discourse. That might do what you’re looking for.


Since a couple of weeks, the plugin allows you to connect a WP page with an existing Discourse topic. However, as far as I am aware you cannot link to a category, or to anything other than a topic.

Regarding the WP Discourse plugin, I have a question. Since we are loading a lot of the post content dynamically with AJAX (normally that would be loaded via single.php/page.php file), we would need some sort of shortcode/function that would display the corresponding Discourse topic for the given page as provided by the custom field in the wp-admin.

Is there any documentation of the WP-Discourse plugin that would explain how this kind of implementation could be achieved with shortcodes/functions for displaying the Discourse topics?

So for example a simple template tag like: get_discourse_topic($post_id); or anything in that manner. Also are there any additional JavaScript triggers needed to be aware of when loading Discourse topics with AJAX?
