In a support thread titled ‘Poll won’t work?’, Neoslayer reported an issue where poll settings wouldn’t open, displaying an error message instead. cocococosti confirmed the feature works normally and suggested testing with manual Markdown syntax, linking to documentation. simon identified the root cause: duplicate poll options trigger the misleading error ‘Poll must have different options’. Neoslayer confirmed this was the issue — they had accidentally pasted the same option twice. simon noted this confusion has occurred before and suggested improving the error message for clarity. Neoslayer agreed, proposing a more explicit message like ‘duplicate option exists’. The thread highlights a usability gap in Discourse’s poll error messaging, with users successfully resolving the issue through community support and identifying room for UX improvement.
Your poll options look good 
And I just tested it in my site and the feature is working correctly.
What happens if you try to create the poll manually using markdown?
For example:
[poll type=multiple results=always min=1 max=3 public=true chartType=bar groups=Discourse,Test]
# My amazing multi choice poll
* Option1
* Option 2
* Option 3
[/poll]

The “Poll must have different options” error message is displayed if you have added the same option twice in a poll. For example, if your poll had two entries for “Great friend”, the error message would be displayed.
yeah, this was it, thank you 
I pasted the same option without realizing
The reason I knew the answer is because I recently helped someone with a similar issue. In that case, we were both confused by the meaning of the error message. I wonder if the error message could be improved to make it more obvious what the cause of the issue is?
Yeah, it’d be nice if it said “duplicate option exists” or something.
