I have a report by a user that for the past week or so updating the training type has not been possible. There is no error page, it just seems to be loading and never finishes. User has Chrome and has tried other browsers with same results. No other problems on the site.
For me, the training page works fine on all computers and browsers I have tried so far (OS X + Windows 7, Safari, IE, Firefox), so I cannot be of any help in duplicating this.
