the links in this site are not search engine friendly links.
the links point to folder roots, for example:
/duke-manchester'
/benedictine-community
/kylemoreabbey-history
site import will look for an index page in the folder root named index.htm, index.html, index.php, indx.asp or index.cfm but no index page can be found in any of the folders. This is causing the import to break.
