can't assign a user specific privileges

I can confirm this issue and it's very critical for us because all our applications are using a separate user and database and we are used to assign schema specific privileges only.

Yes there is a problem when mod_rewrite is disabled (index.php.. is in the address line of the browser) - is this your config?

not really... my server has mod_rewrite enabled. Here's my phpinfo. thanks!

Is chive really running with url rewriting (allow_override enabled?). You can also see this if you finde "index.php" in the browser url?

oh, you're right. when i go to subpages i have index.php in the url. What should i do to make it disappear? in the chive directory i have the .htaccess file chive provides... and on the server i never had problems with mod rewrite (i have many drupal websites with clean urls enabled).
thanks

You usually have to enable the allow_override directive in the /etc/apache2/sites-enabled/000-default config. (just an example on a debian based machine).

On my machine it looks like this:

<Directory /var/www/chive/trunk/>
AllowOverride All
</Directory>

Anyway, good to know that its related to the rewriting, so we will fix this for 1.0.4.
As already mentioned, you can resolve this with the Allow-Override setting until I have provided a fix.
