I was recently editing a post. However, my edit could not be submitted and the error said
It has to be a suggested edit."
What does it mean and does it have something to do with reputation?
EDIT: Based on the answers and comments, I would like to add that I edit the posts quite often without any trouble and always it is visible to me only until it is peer reviewed. However, this time, I could not even submit the edit! The system did not accept the edit and threw the above error at me.
