When i visit Content/Documents & Files in the backend of Sitefinity, the error message, 'Could not deserialize service response, because it was empty or not a valid JSON.' appears, on clicking ok to this message, it continues to loop and re-displays this message box. This only happens with the Documents and Files libraries, images, videos etc are absolutely fine. I do have document files within a number of libraries within Documents and Files, however when clicking on Content/Documents & Files, i get the screenshot below; telling me i have no documents/libraries. If you look at the screenshot of my database though, you will see that i do have libraries in there.
Have you any thoughts as to what this could be?
EDIT: In addition to this, when i insert a Download List widget onto a page, and it lists all the documents i do have; if i then click on one of those files to download, it will download half the file, and then stop downloading.
Also, different browsers display different messages in the backend when trying to view Documents & Files:
IE: 'Return code: 12152'
FF: 'Could not deserialize service response, because it was empty or not a valid JSON.'
Chrome: Nothing, it just displays the header of the backend, with a white page for content.
