Hello,
Addon and Template are not Joomla Extension, so you can not install it via Joomla Installer. I recommend use 1-Click install feature of TZ Portfolio.
To install Addon:
- Go to administrator >> Components >> TZ Portfolio Plus >> Addons >> "Click to Install" button on top left.
- Choose your favorite addon >> Click "Install Now"
To install Style:
- Go to administrator >> Components >> TZ Portfolio Plus >> Styles >> "Click to Install" button on top left.
- Choose your favorite Style >> Click "Install Now"
- To configure style, Go to layouts sub-menu.
If you need further assistant, please let me know.
Thanks & Best Regards,
Sonny
