I joined smartaddons club yesterday and downloaded some templates but was having issues installing the quickstart package. The template i tried was the SJ business. I was getting all sort of PHP error codes, and even when i tried installing the templates only i got an error that i should Please install SJ Core Plugin and when i do, i still end up with the php error codes.

Also, kindly assist me on where to resolve the error "structure or name of file: main-left-right.xml is not exactly" which comes up whenever i try to install the joomla 3x templates and its plugin.
