Hello,
First of all, thank you for your purchase.
I checked and it seems that Quora changes their API structure and also secured it, because of this, the plugin is no longer able to function. I check on this and try to make an update for it, however, probably this update will take a longer time to be finalized, because I will need to research Quora’s changes and reverse engineer their changed API.
If you no longer want to use the plugin because of this long waiting time, I understand, in this case, please make a refund request for it, here: https://codecanyon.net/refund_requests/new
I can also offer multiple alternative plugins, please check them here: https://1.envato.market/coderevolutionplugins
Sorry for this inconvenience.
Regards, Szabi – CodeRevolution.
