Hello, if i use the Nitropack plugin in combination with the booking system of the theme Kingo of Themegoods (https://themeforest.net/item/kingo-landing-booking-for-small-businesses/23385668), this error happens:
“required nonce value is not here, please let the developer know”

The developer of the theme told me to contact the NitroPack developers because according to him it is not a problem of his theme.
Can you kindly help me to solve this issue?
I have momentarily deactivated Nitropack in the website.
Thanks a lot!
