[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

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
