We moved our system from 305 to Umbraco 4 and we are getting errors logged for each url/page in the system and the errors are related to the sitemap provider.

The log table gets filled up pretty fast, and it seems to be triggered every-time someone publishes a page. The number of error logged corresponds to the number of pages we have, so for each page, there is an error.

Did anybody have this problem this before?

How did you fix it?

Details:

• Umbraco version 4.0.2.1

• ASP.net 2.0.50727

• Windows server 2003

• MS SQL 2000

Number of errors with the SiteMapProvider from UmbracoLog Table

Error:

Error adding to SiteMapProvider: System.Web.HttpException: 
'http://www.eurofins.dk/nyheder/update-milj0.aspx'
 is not a valid virtual path.    
 at System.Web.Util.UrlPath.CheckValidVirtualPath(String path)    
 at System.Web.Util.UrlPath.Combine(String appPath, String basepath, String relative)     
at System.Web.StaticSiteMapProvider.AddNode(SiteMapNode node, SiteMapNode parentNode)    
 at umbraco.presentation.nodeFactory.UmbracoSiteMapProvider.loadNodes(String parentId, SiteMapNode parentNode)

Modifing the following methods by removing the "http://" seems to stop the errors in the the log table.

method umbraco.presentation.nodeFactory.UmbracoSiteMapProvider.UpdateNode(Node node)

Code that seems to fix this issue:

//(line 87)
//replace
//node.Url
//by
node.Url.IndexOf("http://")>=0 ? node.Url.Replace("http://","") : node.Url
method umbraco.presentation.nodeFactory.UmbracoSiteMapProvider.loadNodes(string parentId, SiteMapNode parentNode)
//(line127)
//replace in the
//child.Url,
//by
child.Url.Contains("http://") ? child.Url.Replace("http://", string.Empty) : child.Url,
