I’m running on Linux (Ubuntu) and see the same error import OPML files from either Bloglines or Google Reader. If I point WordPress at the export URL for the Google Reader, it claims success, but imports nothing.
At this point I’m thinking the fault is on the side of the WordPress code.
Update:
Still true after the CVS update moments ago. I can delete drafts and posts. I can create a new weblog entry if I hit “Publish” but not if I hit “Save”. Basically once a weblog entry is saved or published, it can no longer be edited. No errors logged that I can see.
Just updated to the latest from CVS, and the problem remains. How was the problem fixed?
