Hi,
Nicolas told me that he will take a look but, one week passed and I see that there is still no answer..
Well, I made the checks and I saw that your plugin "hikashopaffiliate" had an access "registered".
It means that the plugin was not load for users except registered users.. So it can just no work at all !
