Set number of products displayed per page (support thread)

[khuna]

My mistake, I was looking at my oldest log entry. The ones I was getting today was database related. [24-May-2014 14:14:57] PHP Fatal error: 0B_ERROR_NOT_CONNECTED :: select * from zen_project_version WHERE project_version_key = 'Zen-Cart Database' in .../includes/classes/db/mysql/query_factory.php on line 120

Sure:

Invalid arguments passed in .../includes/templates/skate01/templates/tpl_index_product_list.php on line 61

Which seems odd since line 61 is just one of the stock lines and I haven't changed it:
61 // draw music_genre_id
if (isset($_GET['music_genre_id']) && $_GET['music_genre_id'] != '') echo zen_draw_hidden_field('music_genre_id', $_GET['music_genre_id']);
