I first noticed this yesterday, and it's persisting. I'm getting error messages when I try to post edits to one of my posts.
It's being called a permission error.
What's this all about? How does it get fixed?
I just made a successful edit in another post, so this isn't an across-the-board issue, but it does pop up periodically.
It's possible that the issue is restricted to my own OP posts. If so, it's ironic that it is being presented as a permission error.
