It can open but missing some options.

That’s expected when you disable all plugins and themes. But now you know the problem is caused by one of your plugins or themes.
You can try to disable just one of the options to find out whether the issue comes from a theme or plugin

Thanks @Moin

I don’t think we enabled plugins from outside of Discourse the theme we are using were pretty stander.

I am trying to disable some plugin and re-build app.

You’re likely using the MD Composer Extra component. (?)

Once this PR is merged, the issue should be fixed!

I thought you were using MD Composer Extras, because your error is exactly the same as MD Composer extras - #64 by Arkshine. :thinking:

Also, I don’t see any code that requires a change in the PlaceHolder component. However, I can see it was updated 5 months ago to fix a similar issue with the menu.

Did you check if the component has an update?

@Arkshine

I did all updates, before I post a bug here.

I think I found reason for this, was the plugin discourse-placeholder-theme-component cause JS error.

The fixing of this link MD Composer extras - #64 by Arkshine fixed my issue.

The reason for our instance has this issue was because our server hade issue to connect GitHub and cause this plugin didn’t update onetime.

We forked GitHub - discourse/discourse-placeholder-theme-component: discourse-placeholder-theme-component · GitHub to different Git Service and re-pull all code to our instance then issue fixed.

Thanks @Moin @Arkshine and Discourse team for great help.
