HRH Equestrian review for Gratisfaction

As a customer I love to get reward points when I shop, so it was only natural to offer the same to my customers. My only problem is, I can't get it to work. Whenever I hit 'SAVE', i get a white screen with a loading sign that turns and turns forever. It freezes my browser, I have to refresh, and it erases all the changes I made. I contacted support, they told me I might have automatically signed off. So I signed off voluntarily, signed in again, still the same thing. I just lost 2 hours translating everything to get my page in French, and its stuck on loading... Its very infuriating :( Anyone knows how to fix this ? Thanks !
