[Plugin: Ultimate Back To Top Button] It just stopped working

This was my favorite back/scroll to top plugin, and it worked well for quite awhile; but it just stopped working. I’m sure it must be a conflict with another plugin or something.

Anyway, thank you for this very nice plugin, it was nice while it lasted.
