Conversations becoming read-only?

[anon(6098928)]

I am using a Lumia 930, WP8.1 update 1

I have noticed that some conversations cannot be edited/added to within the messaging app. They have become 'Read-only message'?

What does this mean?

Do you have a screenshot of what you're trying to describe? Just blur out the contact details and the text in the messages for privacy.

Based on what I've found so far, it seems that this happens when the contact your were communicating with through SMS in that thread gets modified in your People Hub. You could either try to find out what happened to the contact details of that contact, or you can try starting a new SMS thread with that contact from the People Hub.
