Temporal access
 

I read this in last changes of ispmanager:

New sites use "public_html" directory for storing HTML and PHP pages. This allows use http://IP_ADDRESS/~siteadmin as a temporary address of a site. Old sites still use "htdocs" directory and need not change anything.

Products: ISPmanager Lite, ISPmanager Professional

But I see that new hosts don't use public_html folder and I can't access temporally to http://IP_ADDRESS/~siteadmin

Is this feature actived?

it is valid for new installation.

you should rename folder at site.skel:

cd /usr/local/ispmgr/etc/site.skel/
mv htdocs public_html
