I uninstalled the CB components that I uploaded and tried installing the single CB 2.0 zip file via the extension manager, but it said there was an error. Do you mind checking out the php settings now that the php_uname() error is fixed?
That helped.
Your upload_max_filesize is set to 2M.
You need to update it to at least 6M in order to be able to handle the CB package (and other Joomla extension packages that are more than 2M in size).
