As I want to include some comment funtionality on my site, I've downloaded the CComment Core. I was already a little bit wondering, why only a release candidate is available for download, but well...
So after installing the component I observe the following:
The ccomment dashboard only gives me a sql error message:
Unknown column 'userid' in 'field list' SQL=SELECT COUNT('*') as count, COUNT(DISTINCT userid) as users, COUNT(DISTINCT ip) as ip, DATE(date) as date FROM scom_comment WHERE DATE_SUB(CURDATE(),INTERVAL 30 DAY) <= date GROUP BY DATE(date)
My pages where the comment function should appear fail with the error message
Error: 1054 - Unknown column 'contentid' in 'where clause' SQL=SELECT COUNT(*) FROM scom_comment WHERE contentid='13' AND component='com_content' AND published=1
Looks like something is wrong with the database installation, when installed completely from scratch.
So at the moment the component is pretty much useless

Cheerio
