Hi, Can't delete some documents I've uploaded in the documents folder (Unified File System). The delete button (X) is not active. The access rights settings are correct, webeditors can delete documents and administrators have full access. In one same folder can I find documents that are possible to delete and someone else that are not possible. The files are uploaded with help of advanced file upload (drag and drop). The documents I can't delete get an error msg then try to open Show file information. See the code below. What is the problem and can it be fixed? How can I delete the existing documents? The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL: 1. Add a "Debug=true" directive at the top of the file that generated the error. Example: <%@ page language="C#" debug="true" %> or: 2) Add the following section to the configuration file of your application: Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode. Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario. /Fredrik
