Redmine

Environment: Windows Server 2008, MySQL Database Server, Redmine 3.1.0.

After creating a note in an issue, you can not update the note even you have the required privileges. You can preview the updated note but you can not save it.

I noticed that this error occurs when you use Internet Explorer 11 version. If you use chrome, firefox or IE 8 version this error does not occur. But as an intermediate redmine user i could not find the reason behind the error.

I cannot reproduce on my IE11.
Please give us what plugins you use.

• chrome ok
• firefox ok
• IE11 nok

no JS error in console
