Delete Multiple Web Parts From a SharePoint Page
If you ever need to quickly delete multiple web parts from a SharePoint page, there’s a quick and easy way.
Just add ?contents=1 to the end of the url, directly after the .aspx. If there’s already a query string there (the bit after the ?) then delete it and replace with contents=1.
For example to delete multiple web parts from http://cmis/sites/mis/default.aspx use http://cmis/sites/mis/default.aspx?contents=1.
You can then select multiple web parts and hit delete to get rid of them all at once.
This is also useful for getting rid of web parts which cause fatal errors on the page and closed web parts.
