When entering the New Entry screen (or re-entering it), I receive the following message:
Warning: pg_query(): Query failed: ERROR: Column reference "authorid" is ambiguous . in /home/milo/aaron/public_html/blog/serendipity_db_postgres.inc.php on line 52
As a guess, it might have been something with the re-write engine... Leaving the configuration using ApacheErrors (I think that's what it's called) got me going.
I'm seeing much the same problem on NetBSD. I did try the code change suggested, and got much further, but now it appears to get upset while trying to create the .htaccess file. The last thing in the browser is ``trying to create .htaccess'', and then the box ends.. .htaccess is never created ...
