Hello, I have a joomla version 1.0.15 site and, since I cannot upgrade, I would like to erase it and upload and entirely new site using the latest version of joomla. How is this possible?
To install Joomla 3, you may do so via Softaculous in which there is also an option to overwrite any existing files. Doing so will simultaneously allow you to remove the old site, and create your new installation with ease.
Many things have changed since Joomla 1.0.15 so you may also find out Joomla 3 education channel helpful as well.
