Sorry, shyam541 and BigBear101 for not posting a response to your questions sooner -- since my problem was fixed, I rarely login to this site.
Better late than never...!!
It was very difficult getting a straight answer from LP support, but here is the explanation they sent me:
"Hello,
This issue has been fixed by adding another record on resin configuration file, that has for your host www in front of the domain. So right now in the configuration file there are two records for your domain: one that has host like domain.com and another one that has as host
www.domain.com"
Hope you guys got better support than I did.
Good luck.
