After analyzing network connections of Premium Page I have found that "f=get_fun_price" is not responding from "/stats_new_private/" file. Other requests for this URL are working properly but this particular request is not going through. So maybe it is some issue on server side related to get_fun_price function, maybe an expired API.
Hopefully team will correct it soon.
@TheQuin is not here for few days so just because of this we are having this error as he will be back all will be settled.
We have to wait for his return with he is taking too many vacations, but no one can do anything in his absence, hopefully all will be back to normal in next few days with new bets are also needed to be posted.
