I could not access your admin thus not sure if you are using any 3rd extension? I tried to disable your theme on your site, the issue still remains. That means the bug does not come from our theme.
I’ve sent the credentials in private message.
Please let me know if you can solve the problem
Your site used Belvg_FacebookFree extension which caused this bug. I had Belvg_FacebookFree extension disabled, it works fine then. Please check again.
