We have a webpart running on SharePoint 2010 that displays our latest news that has been in use for at least 3 years. As of yesterday, it stopped working. It displays the webpart with title and the button linked to the news list works, but it does not show a preview of the news item, scroll, or have buttons to move between different news items. There is also an error displayed below it:
[Control] An exception has occurred. Object reference not set to an instance of an object.
Nothing has been modified on this page, in the list, nor have the webparts been changed. Googling doesn't get me too far either. I did see people relating that to low disk space, which we were encountering and has been taken care of but still this webpart just won't work!
