    Validation: A content type, media type or member type with this alias already exists

    Picking up an existing Umbraco website and in the Media section I can see a Media Type of Resource.

    Yet when looking in the Settings section, there is no Media Type called Resource.

    When attempting to create a new Media Type called Resource, I am getting the following error message

    Validation: A content type, media type or member type with this alias already exists

    Any ideas why this might be happening?

    If anyone else comes across this, below is how I resolved the issue.

    For some reason, the parent ID in the database table umbracoNode for some of the Media Types had been changed from "-1" to a random value. Due to this change, I was unable to see the Media Types even though they still existed.

    By changing the parent ID back to "-1" I was now able to see the Media Types once again.

    As to what this had happened am I not sure. My gut instinct is that it has something to do with uSync.
