Comments are not currently working in my installation of UNG. I’m aware of the problem, and as I’m the only active developer on the project, I’m working on fixing it. No worries.

As I see it, the problem likely comes from Dreamhost running PHP as a cgi and previously all my development and testing being with mod_php. Either that, or it’s a problem with the way I’m integrating WordPress into my site layout.

The symptom is that even though I’m setting the MySQL database with mysql_select_db(), it’s still trying to use the WordPress database. Setting the $link_identifier helps, but only sometimes.

Anyway, I’m working on it. There will be a new version of UNG once I fix it.

Edit:
It’s fixed, so far as I can tell. Check it out, if you care.
