central server doesn't "know" remote nagios servers anymore

[Inbeller]

I've installed a central nagios/centreon with a remote nagios.
All went well. Uploads workes, monitoring was ok, ...

I've copied the /var/lib/centreon dir to a new lv.
And I've set the permissions (I think) to what they should be.

The config files for the remote nagios server are created in /usr/local/centreon/filesGeneration/nagiosCFG/2/
In the /var/lib/centreon/centcore.cmd file, I see
SENDCFGFILE:2
RESTART:2

But the upload fails. The apache error log is empty.

Can anyone help me with this please.

Ok, it's a permission problem.
/var/lib/centreon should be 775

I know (now) the installer asks to set it like this too.
Maybe something to put in the documentation.
Which files/dirs should be owned by which user with permissions xyz.
