Adding a domain causes disabling others in vhosts file

[vprocopan]

The first domain isn't the only one that gets disabled, when i make changes, But I'll try to remove the first one (amoresparaiso.com) that comes with :80 port, tomorrow at 5:00, so users we'll be sleeping, hopefully it will fix something. Do I have to edit it manually to remove the second port from vhosts, or do i use the apache module admin? (Im asking about the structure integrity of the vhosts file)
