Came up against something I haven't seen before and don't really know how to fix. The French site structure has changed substantially in the last year (not sure when), as part of a reorganization that enables them to have various different paths to the same page content. There are now three locations for undergraduate course info:

• graduate/undergraduate/courses/index (up to date)
• undergraduate/undergraduate/courses/index (mirror of above)
• undergraduate/courses/index (mirror of above first page)

There seem to be two paths through the menu structure to this content, prospective-students/undergraduate/courses and current-students/undergraduate/courses (no idea why three copies are needed). Whichever way you go through the menus, though, you no longer see "prospective-students" or "current-students" in the url path; you just see either undergraduate/undergraduate/courses/index.php or graduate/undergraduate/courses/index.php. But it looks like there were once paths including "*-students", and content was published to those paths and never unpublished. As a result, there are ghost pages up on the site, which have out-of-date info and broken links. The link-checker keeps flagging those pages, but I have no idea how to remove them since there's no equivalent resource I can see on the Cascade system that I could unpublish. Weird. Waiting for advice from LG.
