Okay. I fired up my old sentora server and did some tests
I can install xbilling fine on the old one, and not the new one
Did some poking around, the old server has everything set to root as owner,
I followed the zppy command back down the chain and the only difference I can find in permissions and file access is
/etc/sentora/panel/bin/zsudo
On the old working server its set to
-rwsr-srx and the filename is red
on the new server its set to
-rwxr-xr-x and the filename is green
as far as I can tell, all the other permissions are the same between the two servers?
