Hi, good afternoon:
It would be nice to know what modifications you need to make. The template and plugin are updated to the latest version and the error remains.
As you will surely understand giving access is not something trivial and as it is a persistent error, please tell us what data you need or what modifications should be made and we will do it.
Thank you.
PD: another option is that you tell us the IP from where the action is going to be performed and the date and time, to enable the connection.
