Just upgraded to 3.5.1 WP & updated NexGen plug in. Now images/slideshows are not appearing (Getting 'Error - file not found' on front end). In admin, in some of the NexGen galleries the images & thumbs don't show - this is a sample path to a gallery in the Path: field /wp-content/plugins/nextgen-gallery/yuri-gallery
And if I scan for new images in that folder I get an error message with a really long url & a message that the directory doesn't exist.
Any top tips to fix it? Tried deactivating plug ins/reactivating etc...
