Error when dealing with Documents library

Hi,

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.

Thanks,

Louis

Hello Louis Farrell,

Can you send us backup of your database and App_Data folder in order to investigate what is the problem with documents?

Thanks in advance!

Hi Louis Farrell,

Thanks for you responses Milena!

I will create a ticket soon with our database and app_data included.

You said it in your latest response, 'We found similar problem as the issue you are reporting with this ticket and we fixed it.' But no reference to a ticket? I am just a little interested that is all.

Thanks for your help!

Louis

Hi,

I am opening a Page Template of my own in design mode. I click Publish and I get the attached error message. I cannot publish my templates any more.

Many thanks,
Andrei

P.S. All my pages and templates do that now. 

Guys, any takes on this?
Thanks

Hello Andrei,

Please check whether something blocks the web service call. You can easily observe HTTP request and response with Fire Bug and its Net tab. Also check for some js errors.

Ivan,

I started all over again.
I am just getting FireBug now for future issues.

Thanks,
Andrei
