This is a duplicate of #3652

[thuyduongnsx@…]

I read #3652 but I didn't try to create any milestone with the same name as an existing one.

"If you try to create a new milestone with the same name as an existing one, you get a python error message and traceback. This should be handled gracefully with an instruction to the user about choosing another name."

And after that I don't make any thing special such as new line or bold text, italic text. Simply I type some text, but I always get this error, and can't add any milestone

Please help me! Thanks very much!

I had to infer milestone creation by looking at the traceback, you didn't actually give me anything to go on. Describe your error completely, please. What milestones do you have currently? What is the name of the new milestone you are creating? Can you attach a screenshot of how you're filling in the fields, if nothing else?

Duplicate of #6808.

(also inferring from the description, I guess he must have missed the milestone name part, and has tried to create more than one unnamed milestone...)
