I click the wrench icon and choose ‘Delete Topic’.
The invite button is grayed out, but the topic is not removed. I go back to the main page and I can still see it. I hard refresh the page and the topic is still there.
I checked the console, and there are no errors. I am also the admin of the site and the one who wrote the question. I assume if there was a permission issue, I would have seen a notification or the delete button shouldn’t be there in the first place.
This is a UI issue – I get the same thing when deleting topics here on meta. The UI doesn’t display the delete, e.g. make the background of the first post the light red deleted color, etc. But it’s there.
I don’t think we’ve bothered to improve it since it’s a cosmetic issue only.
