Not working with WHMCS 8.11.1

[jmiaje]

Hi,
First of all thank you so much for maintaining the repository. I have tried to make this one work with WHMCS version 8.11.1 but unfortunately its not working for me. I mean even i have successfully installed it but it is not applying the fees on the gateway.

I have tried to apply the fees on stripe gateway with amount perchantage but the output is none. It is not adding anything at all.

Can you please check the issue?

Thank you,
