SharePoint Web Part Page: Contents=1

An oldie, but a goodie piece of SharePoint advice. Eloquently put on blogs.msdn.com:

“This is probably the most useful of querystrings. Using this on any "Web Part Page" will take you to what is called the "Web Part Page Maintenance" page (screenshot below) which allows you to delete web parts from both personal and shared views. This feature is especially useful if you have added a misbehaving web part. In this situation you can find yourself in a "chicken and egg" situation, whereby you can’t access the page to remove the web part because the web part you have added is causing an error on the page.”
