Hi all, We recently rebuilt our forums to use 2026.4.0-latest and now users cannot view past votes and are having trouble voting. I have checked the logs and it looks like Topic Voting plugin may be using deprecated features. Here is the stack trace: activesupport-8.0.5/lib/active_support/broadcas…

Any chances this has been fixed by [image] FIX: Add CORS header for all `/assets/*` (#39031) · discourse/discourse@2790b17 In a standard install, where assets are loaded from the same-origin, this makes no difference. But when a CDN is used, this CORS header is required for `type="modu…

This is a very important plugin for our community so would appreciate this issue being investigated asap.

我也遇到了！！！这很令人沮丧，因为我作为discourse用于自身项目大量使用了poll插件进行投票，我从三个多小时前就已经在开始想办法处理这个问题但一直都无法解决，希望官方能够出面处理，不然就只能找其他已有平替了(目前暂未发现有替代品)。

This issue also seems to be impacting Reactions Plugin and the User Note Plugin with users reporting that these now no longer work. Again it seems to be related to selected_tags param being deprecated. I would expect now that these plugins are included in core this issue should have been identified …

The versions 2026.3.0-latest and 2026.3.0-latest.1 also experienced the same issues as reported in this post.

It looks like other plugins are also impacted by this issue: Calendar and Events Solved Might be here where the issue lies? discourse/app/controllers/topics_controller.rb at 46e769b605d782dfee5cf1f6cb26571e42e9c431 · discourse/discourse · GitHub

[image] tanya_byrne: removal in Discourse 2026.07 Currently, this warning should not cause any issues.

I’m not seeing any other issues in the logs related to these plugins. Is there anything I can run to help diagnose the cause of these issues?

Do the plugins work for you? Do the users who report that they are broken see more errors in their browser console? The fact that your problem seems to affect all plugins reminds me of this recent topic All plugins not functioning due to CORS error after recent upgrade

hmmm, I had a look at the dev console and am seeing a bunch of CDN errors so will dig into this further! This might be the root issue

As an aside, I don’t use bunny CDN but are seeing `app.js:73 Failed to load plugin discourse-local-dates from TypeError: Failed to fetch dynamically imported module:` where the JS is on the CDN
