Does anyone here work on the Wordpress plugin?


I found a bug in the WP plugin and reported it a couple of days ago, including how to fix it. Haven’t heard a peep so far, and it’s causing us some problems. Does anyone here work on this project, or know someone who does?

Here’s the issue:

This seems to have only become a problem since we updated to WordPress 5.5. The actual problem occurs in the initialize_update_user_route method of the SyncDiscourseUser class. Apparently register_rest_route now requires that you have a permission_callback . I added 'permission_callback' => '__return_true' after line 53, and the problem went away. We are using WP Discourse version 2.1.2

Thanks in advance,



This is the correct place to report. Its mentioned in the support section of plugin.


It should get seen here. You could also submit a PR at GitHub - discourse/wp-discourse: WordPress plugin that lets you use Discourse as the community engine for a WordPress blog

Sorry about the delayed reply to this. Your suggested fix will work.

The webhook request is being validated in the call to verify_discourse_webhook_request, but there isn’t an explicit permission_callback on the route - it sounds like that fails in WordPress 5.5. I had thought it would just give a deprecation warning.

I’ll update the plugin with your suggested fix for now. Later we can look into calling the verify_discourse_webhook_request from the route’s permission callback instead of from the its callback.

Edit: WP Discourse version 2.1.4 adds an explicit permission callback to the update-user REST route. It’s in the WordPress repo now.
