There must be something in layer-z-order above your slideshow. If not we would need a reduced to your issue muse-file.
You can tell Muse to upload, www.yourdomain.de/whatyouwant. If this folder does not exist, Muse asks you, if "she/it/" should create this folder. Does this help? Am not sure, what you mean: behind my existing side
Thanks so much! You've just triggered me to be able to figure it out. I hadn't realised that I could nominate a new folder. Was a bit of pfaffing (my inexperience), but I've got it all working now, with a redirect from my original store.
Really appreciate you taking the time to answer.
And yes - the slideshows work fine, when uploaded directly from MUSE ftp.
You are welcome.
