We are using DNN 7.x. When we update any of the page settings and save them we get duplicate .aspx extensions on the end of the urls. So instead of:
mysite.com/mypage.aspx
we get
mysite.com/mypage.aspx.aspx
Of course this breaks the path and throws a 404 error from any links within a page.
Does anyone else have this problem? How do I fix it?
