Thanks for the info. In fact that is what I had done but still I ended up with the oldsite.com/newsite in the address.
I can't explain why it is happening, but I have figured the problem. Maybe this will help someone else.
My main site is not an issue.
When I added a domain and then used the Canaca Software service to install XOOPS, I ended up with mainsite.com/newsite in the address.
I manually copied the same files to a different "Add on domain" and did not get the same issue with the address.
Perhaps someone has an explanation. For now, I have found a solution, and that is for me to upload the files manually rather than have Canaca do the install automatically.
This is no slight against Canaca by the way, I am pleased with their service and price.
Optimism is the mother of disappointment.
