Dear Sir / Madam,
I am attempting to Integrate WHMCS in to my WordPress site and I am confident I have followed your detailed instructions in setting it up, however I am getting a "WHMCS Integration: Failure when receiving data from the peer" notice.
I have created a username and password for you to login in to WHMCS admin to make sure I have definitely set it up properly (which I will share with you once you email me)
+ I will make sure you can access the WordPress site as well.
I am usually able to set these things up, but I am really having an issue with it at the moment.
