Thanks to both of you.
I understand the concept (local vs remote), but still not sure what to do in the WA_globals file... I am not using a local server at all, just uploading to a remote host. Can I keep the localhost line commented out? Do I set it to the same as the remote host? (in my case $WAGLOBAL_remoteRoot = "/CMS/") Or does it matter?
Please be specific.
