When the weather feed is not currently available from either MSN or Yahoo!, there are times when your page will hang on loading and you might feel as though your page has completely broken.
A quick and simple way to remove to the web parts that might be causing a page load issue is to look at the web parts maintenance page. To do this, add a string of characters to the end of the URL in your address bar
?contents=1
Example: http://CompanyName/sites/SitePages/default.aspx?Contents=1
This opens the Web Parts maintenance page showing you a list of all the web parts that are on the page so that you may delete any that are causing conflicts. Be aware of which web part you delete; this is a permanent action that you cannot undo! Typically older versions of web parts or web parts using JavaScript or JQuery code may be in conflict. By removing one at a time, you can determine the one causing the issue.
