When I click the link of Aggregate Feeds,  I got a page showing "We're sorry but we could not find the page you are looking for. Please try the Site Map."

Then I found following error information from system log.

I get it, thanks.
I built my website by working  with source code from trunk. 
I found some resource and image files are absent ,and I guess some source files are not lastest, would you mind rebuilding a new version, and submit your all source files in your project to svn server,  just do it at any time,thanks

best regards,

xgma

yes, I use the VS Publish feature , I am going to rebuild and make a package with unleashit
thank you very much

best regards,
