I relize that with 2013 the designer "design" view is no longer available. (I guess I can live with that) BUT My problem is anytime I update a page in code view, desiger 2013 either gives me this error:
It then either removes some or removes all code (resulting in a blank page)
or causes an error:
This happens if I just put in a space and then remove that space and save (not changing anything at all)
This happens on my old 2010 pages as well as my new 2013 pages. It appears designer kills them all.
Any ideas as to what the issues is would be appreciated.
