We have received numerous support emails and there is a very long thread about the editor not saving changes. Unfortunately, the amount of information in each report is not enough to diagnose the issue and I am unable to replicate it here. If you are having a problem, please leave the following information in this thread:
1) Blog address (URL)
2) Whether you are editing a post or a page
3) The ID of the post/page you are having problems editing. If the post is published, a link to the post will work just as well.
4) Whether you are using the editor with the two tabs (Visual and Code) or the editor without any tabs. If you are using the tabbed editor, which tab are you writing in?
5) Which browser you are using (Firefox, Internet Explorer, Opera, etc)
6) Specific details of the problem. (what you were trying to add to the post, what (if any) errors were present, etc.
I am closing other threads on this issue and any post in this thread without the necessary information will be removed as not to confuse things.
