xBilling variables problem and vouches

[Fuzzy]

No, I don't think it should. What does apache log have to say about the error?

OK so it seems to be a permission error, I cleared the log and tried again and got (among all the other vhosts with active e-mail accounts)...

Code:

du: cannot access '/var/sentora/vmail/MYSITEVHOST.COM': Permission denied

Also, I don't know if it's relevent but got this below the above permission errors:

Code:

[Sun Oct 04 15:15:02.066869 2015] [mpm_prefork:notice] [pid 4081] AH00171: Graceful restart requested, doing restart

[Sun Oct 04 15:15:02.743301 2015] [core:notice] [pid 4081] AH00094: Command line: '/usr/sbin/apache2'

Do I need to chmod something somewhere?

EDIT:
I have tried chmodding "/var/sentora/vmail/" to 777 just to see if it was that but now I get no permission errors in the log but still get "API Error:" on the billing front end.
