Hello,
I m using Joomla v3.0 and trying to install extension Spreadsheet v2
im getting this warning…
Warning
JInstaller: :Install: Cannot find Joomla XML setup file
Unfortunately Spreadsheet v2.0 beta doesn’t work with Joomla 3.0.
But we are preparing v2.0 release for now. It will include version for Joomla 3.0.
It will should be released today.
