CF8 and Apache

Have CF setup as a multiserver instance.
Have two other instances and one default (wsconfig/1)
Two others are called "Paris1" and "IT"
These were created no worries with no errors.

Setup the instances and they are running fine.
Then the VHosts are correctly configured too.

All sites on the first instance open fine.
But the other sites on the other two instances only work if served by apache and only as html sites.

Have uploaded the apache error log but it points to CF being the problem to be CF.Have also uploaded the CF logs.
