[Zope] Add another site’s content to Zope

Hello, I want to add the another site's content to Zope. I used that description https://weblion.psu.edu/trac/weblion/wiki/AddAnotherSitesContentToYourZope but it doesn't work with each site and in particular with www.ecocoms.com . When I try to do that with this site and choose the site language /bg or /en from the home page I get an error: "Site Error An error was encountered while publishing this resource. Resource not found" Can you help? Seta Kramyan
