Bitcoin option not working

Hello
I just realized that Really Simple Share added a bitcoin wallet donation option. That’s great!!! So, I entered my wallet (public key), address in the specified place, and the counter keeps spinning, also when I click it, it refreshes the page, instead of directing to a bitcoin wallet/QR code..any one using this option?? Thanks!!
