Hi,
the following messages appear, after installing K2:
********************
Warning: Invalid argument supplied for foreach() in /home/ha000154/www/home/PR20/libraries/joomla/database/database/mysql.php on line 678

Warning: array_key_exists(): The second argument should be either an array or an object in /home/ha000154/www/home/PR20/administrator/components/com_k2/install.k2.php on line 72
*********************
If I ignore it and try to create an Extzra Field Group I get the following:
*********************
tablek2extrafieldsgroup::store failed - Table 'ha000154_jo.jos_k2_extra_fields_groups' doesn't exist SQL=INSERT INTO `jos_k2_extra_fields_groups` ( `id`,`name` ) VALUES ( '','Presseinformationen' )
**********************

This is the show-stopper!
I found some similar posts, but no solution. Can please anyone help?!

Here are the details of my installation:
PHP 4.3.11
MySQL 4.0.24
Joomla 1.5.15 Stable

Thanks in advance and best regards
Gernot
