It is the TelinV template with Joomla-3. On this website it works.
Mr. Saguaros, with great respect, I do not understand why you are asking this question. For me it is very clear. On the right side where I have pointed, I want to add a sidebar or sidebar-1 or sidebar-2. But none of them work. However in telinev joomla-3 it works with Sidebar. I hope it is clear now. Note: The superuser "Pankaj" is the same one I put above, but not the "Host".
