I have installed Sitefinity 3.7 sp1 on server running Windows Server 2003 R2 with SP2 and .NET Framework 3.5 sp1. Then I created a test site successfully. When I logged on to administer the site, there were some rendering problems on pages. Main menu was shown incorrectly as well as the page "Edit this page", etc. Also, at the bottom of the browser, the scripting error message indicate that 'CMSPageViewer' is undefined and 'SiteMapPanel' is undefined.
Please tell me what is the problem.
