Sometimes when opening a SharePoint web part page you will see an error that references the ability to go the Web Part Page maintenance.  This allows you to remove any web parts that you think might be causing the error.  This is very useful, if it comes up.  I just recently came across a scenario where ther erroneous web part was closed on the page (which means you can only see it in SPD, and that no error occurs in the browser).  When trying to access the page in SPD I get an error that say I cant open the page and should try the web part page maintenance.  The downside is that this error message does not give you a link to that page. 

 

So here is how to get to the web parts page maintenance for any page.  Simply navigate to the page with the issue and ad a query string 'contents=1'.  For example navigating to http://intranet/default.aspx?contents=1 would take me to the web parts page maintenance for the home page.
