Hi, this is probably related to this previous problem that you fixed before where options weren't being saved, post link at the bottom.
And that is, AUTHORS on my site cannot post a post that has an ordered list like:
- one
- two
- three
The post LOSES the list numbers completely when you post. Admins CAN write ordered lists, Authors cannot.
If I disable Media Uploader things work perfectly.
This happens with NO other plugins, and the Twenty Sixteen theme.
Look at this previous post where you fixed a similar problem, possibly related.
Thanks!
Charles
