When I check the subject setting to yes, SEF URLs are indeed different for entries in all categories, but in category view, title of not all entries link to the details page. I have all entries in 4 categories, and for each entry (in categoy view) the title in only one or two categories actually link to the details view; for the rest clicking the title simply reloads the page. I'm have SOBI2 as the home page. Please point if this is a resolved problem. I've just installed everything, so the versions are current. Thanks
