Ro,

How do I turn off members ability to edit a previous post?

I'm assuming you mean a post made by that member, a member cannot edit other people's posts.

There isn't a general control to disable that capability.

If it is a specific message you are concerned with then one thing you can do is Close the thread that message is a part of. After a thread has been closed its messages can no longer be edited (but they can still be deleted). That's a recent bugfix.

Of course, you may not want to close the thread to all new messages, and it wouldn't prevent the member from editing their other posts.
