clan war results no longer saved

I’m experiencing this issue since few days (maybe wordpress update?).
I just updated the theme to 1.9.7 to see if the issue were solved, but it’s still there.
As I edet matches to enter the results, it shows me “match updated correctly” but the results is 0:0 all the time.
Can you please help me? This is REALLY important, i bought this theme only for clan wars..
My website is http://clandecima.it

Everything worked just fine until 9 december, things started to not work from 10th.
