We're getting an problem removing an element in Joomla Extension Manager but simply realized the sub menu [Install Component Modules Plug ins Languages Templates] is missing.

Any ideas why this maybe? Your reactions are appreciated ahead of time.

Thanks IMVBank

Probably the most apparent factor to check on could be your admin level. You need to be webmaster or Super Administrator for that Extensions menu (where Install is situated) to even appear. If you are a supervisor or lower, you will not connect.
