I have been using this map for two years now and and exporting maps. It was working fine last week. Today, it started giving me this message. The map is data driven and uses online content. Any thoughts on how to fix this?
Strip out the online content, this sounds like a cause - not the solution but at least it identifies the issue.
Try the MXD Doctor utility.
Give more details on your export settings etc.
MXD doctor didn't do anything.
So after reconstructing this map and testing it at all phases, I have discovered that the issue is when I create data driven pages. For some reason, I can not export pages that are data driven. Any thoughts?
