Uninstalled 2.0, installed 1.8
Button is back and works.
Hi Jeriff, V 1.8 was working perfect for me.
It had the “Scroll Back to the Top Button” appearing any time I scrolled down, perfect!
Now since I updated to 2.0 the button disapeared and there is no option avaiable anymore. Is there any way I could install V 1.8 back again, or would you correct this in the near future?
Thanks for your feedback
