In SharePoint, when an error occurs in a web part that prevents it to be rendered on the page, an error page is displayed to the user with a link to the web part maintenance page. This page lists all the web parts that were added to the web part page and their current state, allowing you to remove web part that is causing the error.
Although this page is very useful, accessing it is not as easy as one would expect. There are two ways to do so.
- Go to Site Actions > View All Site Content
- Open the Pages list that stores the page about which we wish to get information
