[smokeping-users] Problem showing graphs in OPenSUSE 12.3

Thanks for the posts. I verified all of this before I posted the
initial message. I think it is working now and it turned out to be an
Apache permissions error. The user/owner were set wrong on the www
directories and giving them explicit rights in advanced permissions did
not work. I rest the permissions on www and applied them to all sub
directories and it is now running.
Thanks again to everyone who assisted.

I verified all the locations for both /opt/ when i tried installing it
from source and /etc/ when I installed it from the repository below

I will keep in mind the --/logfile in case I ever have to troubleshoot
smokeping again. I did try the --debug and checked the standard and
Apache error logs.

I used the repository this last time so the location of most of the
files /etc/ instead of /opt/ other than being required to use https in
cgiurl this matches what I have
