Migrate from VHCS2 on Server 1 to ispCP on Server 2

[DaSilva]

Now I have a new problem.
This is very strange.
If I create a test file in /htdocs I can open it without a problem.
After that test I have used Unison to synchronize the whole domaintest.tld from server 1 to server 2.
The synchronisation works like a charm but if I try to open the page on the new server I always get a 403 error even if all files have the right owner.
How could this happen and how can I solve this problem?
Thanks.
