impossible to update payments settings
i've been hacked and backup everything.
everything is fine except that this page "admin.php?page=app-payments-settings" and all tabs are impossible to update. see attached
i also see that the symbol of the currency in this page does not load (see attached)
For the theme he is telling that "the page has been updated but nothing change
i've try to change permission, no results
any help will be good because i cannot check"pack" and paypal also
