This is done & rebooted but still get the 500 Internal Server error when 
try to connect to either http or https.
/var/log/perfsonar/web-admin is empty - should it contain something? What 
should generate something in there that is not?

Does that all look ok permissions wise?

/var/log/httpd/error_log still full of permission denied:
[Tue Aug 25 15:24:00 2015] [error] [client 128.142.136.248] Cannot write 
to '/var/log/perfsonar/web_admin/web_admin.log': Permission denied at

I touched /var/log/perfsonar/web_admin/web_admin.log to create it & then  
chown apache:apache /var/log/perfsonar/web_admin/web_admin.log
then restarted httpd; but it doesn't seem to have made any difference, 
still 500 Internal Server Error. Does it need wider permissions?

Very Grateful for your help+advice!
