ReportServerUrl element is not a valid configuration file element

Hi,

I get the error specified in the subject

"ReportServerUrl element is not a valid configuration file element"

ini the report manager if I replace

<ReportServerUrl></ReportServerUrl>

tags in RSWebApplication.cofig file with

<ReportServerUrl>http://<computername>/ReportServer</ReportServerUrl>

Any ideas why I should get that?. If the element was not valid, it should not have worked even earlier?

Thanks.

Have you also set ReportServerVirtualDirectory ?
Take a look at: http://msdn2.microsoft.com/en-us/library/ms155878.aspx

ReportServerURL and ReportServerVirtualDirectory are mutually exclusive. If you specify ReportServerURL, you must delete the entry for ReportServerVirtualDirectory
