Counting doesn’t work

Hello,

I use the plugin on my website cash-geek.com.

I insert it via shortcodes [favorite_button site_id=”5333″] and [user_favorites].

There are 2 problems: 1. when I klick on the bookmark button the number increases by one, but when I refresh the page the number decreases. For example on this page: https://cash-geek.com/blog/2017/04/06/biznet-long-term-investment-with-up-to-30-monthly-profit/
2. The favourites list is blank. You can see it here: https://cash-geek.com/my-bookmarks/

Please help me. Thank you in advance.

Best regards,
CashGeek
