Ok I used the cleanup method and by mistake I selected the "delete from poster wall" I should have selected "delete from wall and put into unmatched" How do I get films back in the wall ? The films still exist on my media server so no worries about source.
Once you delete a movie from the posterwall it's flagged as permanently removed in the database and just rescanning doesn't bring it back. You can either rename the movie you've removed (maybe add the year at the end or similar) and rescan, or you can clear the source (clean up) or remove the source and rescan from scratch. Easiest is probably to rename the movie.
ok, thanks good information. It would be good to see a list of excluded items, but I must be more careful
It can be a nuisance - done it myself a few times, but you can see the logic - if you specifically want to remove an item from the poster wall you don't want it turning up again every time you do a rescan.. So it kind of makes sense.
