Greetings,

I'm using the Community plug-in in a testing environment - adding various users and working to get groups and permissions set up etc. Then I invariably hit a point where the program explodes:

Warning:  [mysql error 1064] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '18)' at line 3

  SELECT id, name, permalink
    FROM piwigo_categories
    WHERE id IN (,18)
  ; in /home/tommytdl/foto.rocktumblinghobby.com/include/dblayer/functions_mysqli.inc.php on line 845


Fatal error: Call to a member function fetch_assoc() on boolean in /home/tommytdl/foto.rocktumblinghobby.com/include/dblayer/functions_mysqli.inc.php on line 898

This explosion is always followed by mulltiple error messages at the top of the screen:

Notice: Undefined index: in /home/tommytdl/foto.rocktumblinghobby.com/include/functions_html.inc.php on line 140

Piwigo 2.9.0
