If you add a web part to a page and it wasn’t written correctly you may experience an issue where the whole page doesn’t load.

When this happens, the simplest way to solve the issue is to perform the following steps:

• Add the string ?contents=1 to the URL of the broken page – e.g. http://intranet/pages/default.aspx?contents=1

• This will take you to the Web Part Maintenance page.  Once the page has loaded, look for the web part that you think is causing the error.  In most cases, it will actually display Error in the web part name.
