Its OK I had not assigned any services, however now I am getting the error: Source IP not allowed: 74.53.76.24, I read the install files and it says:

You must add your site IP to the Moodle trusted XML-RPC hosts list, in Moodle Admin->Networking->XML-RPC Hosts

But I can not find this, any guidance please

You need to enter that IP as Internal IP Address, in Joomdle configuration in Joomla.
