I had the same problem with the new version 3.4.8. I am running my site on WP 3.9.2 and uninstalled the wptouch 3.4.8 and used an older version 3.2.1 and it works fine now. For some reason the new wptouch is adding the menu to the side instead of top and won’t let you scroll or change the position. If you need help getting the older version, let me know.
