I have facing an issue that Sitefinity shows the "undefined" message when I try to create a new content. It returns "500 Internal server error". The text I used to fill the Title field is "MAN FINED $7,600 FOR ILLEGAL IMPORT AND POSSESSION OF WILDLIFE test". I saw that it has the special character "$". However, Sitefinity doesn't remove it from URL name under More Option section. Instead of show "undefined" message, it should show "The URL XXX is invalid."
I cannot figure out why so. This is a video I have recorded https://www.screencast.com/t/b7mQcQSb
Please help to advise on this
