Last LiveChat error when buy a service

[juans]

Hello,

We just installed the live chat and it works correctly. We installed the latest version V5.4.4284, on the whmcs version 7.1.1

 

Now the problem is when we try to buy a service, in the option "i will use my existing domain and update my nameservers", when the livechat is installed, it does not go to the next screen. And in the screen always show the text "verifing your domain selection . . ."

 

There seems to be a clonflict in this case. Then if we uninstall it, the purchase of the services works correctly.

 

Can you help us?

 

Thanks!
