I’ve got it. It happens when you use two spaces after a period instead of one. It’s got nothing to do with the AJAX call but seems to be a bug in the editor.
This has also been happening to me at http://www.nomadicsiren.org/japan/ since upgrading to 2.5. It’s as simple as:
- Start a new post
- Enter “This is one sentence. This is two.” in the main post area.
- Hit Save
Everything disappears except the first sentence.
Looking at the AJAX calls that happen on a new post, I think this is the culprit:
http://www.nomadicsiren.org/japan/wp-admin/admin-ajax.php?action=autosave&autosave=1&autosavenonce=3f42d5a148&catslist=&comment_status=open&content=This+is+one+sentence.%C2%A0+This+is+two.&excerpt=&ping_status=open&post_ID=298&post_author=&post_title=Test+sentence&post_type=post&tags_input=
Check out the weird characters after the first sentence.
What web server software are you using? I’ve only got experience with WP under Apache but I’ll give it a try if you’re using something else.
