SharePoint “List does not exist”

Question

Ok so I seem to be the only administrator managing a SharePoint website on behalf of the Health Service. However being as it's linked to the government someone made this website for free. I also assume that he made some of the webparts himself.

One of these web parts was an FAQ webpart which enabled you to created FAQs with a fancy format. Now however whenever I try to make an FAQ I can select it and it will now be ready to edit. Now however when I go to modify it, it will take me to an Error Page which says:

"List does not exist

The page you selected contains a list that does not exist. It may have been deleted by another user. Troubleshoot issues with Windows SharePoint Services."

Does anyone know how to find out what the webpart is looking for. What the list is called so I can make another one to replace it? Tried looking in the ".Aspx" for the page but it doesnt keep any information on the webpart. Any ideas or pointers would be very greatful.

Thanks for looking

Answer 1

If he has coded the web part himself check the Application logs on the server as he may have written an error message there specifying which list it can't get to.

The other way around this is to see if the web part is working anywhere else in another site or location. If it is compare the view all site content areas and see what lists don't exist in the site that is failing compared to the site that isn't.

Another route(may take some time) is to get a tool called reflector. Drop the web parts dll in to this tool which then allows you to go through the code. This is all dependant on how experienced you are in coding etc etc

Hope this helps
