I have a few Content Query webparts added on a webpage. However, someone is changing the query in the webpart because of which the desired results are not shown. We tried to check who is modifying the query in the Content Editor webpart, but even if we change properties of a webpart on SharePoint using IE, the last modified date and the Modified By fields do not change. Because of this, I am unable to determine who is making the changes and when.
Is there any way I can find this so that I can take the necessary actions.
