I upgraded from 6 to 7. Also got a new computer so I moved everything over. I have 2 different pages with videos (see below). But both pages are playing the same videos on my site. Made no changes to any settings. And it looks fine in RW and Preview.
Go through your RW7 project and ensure all pages have unique names. Then, using ftp, delete the folders currently on the server and republish all pages and resources.
Thank you for catching that! Before deleting and republishing, I changed the name of the folder for one of the pages in General Settings. Fortunately, that did the trick.
