If your virtual tour is published but is not showing on the front-end there is usually only 1 reason and that is that your images are too small.
To protect you from yourself – and to make sure your image quality is the best on each tour you have to upload images that have a minimum dimension of 5000 x 2500.
If your images are too small, the tour will not load. Check that you didn’t accidentally resized the images too small when you edited the images prior to upload.
To replace the images in your tour, simply upload them again in the correct size using the same file names and the tour will automatically be updated with the correct image. Now you can view your tours 🙂
