When I select the categories block (eg HP) I get the following error.

I am running PHP >4.2 not 5 and apache 2.20

1054 - Unknown column 'p.products_id' in 'on clause'

select count(p.products_id) as total from xoops2_osc_products_description pd, xoops2_osc_products p left join xoops2_osc_manufacturers m on p.manufacturers_id = m.manufacturers_id, xoops2_osc_products_to_categories p2c left join xoops2_osc_specials s on p.products_id = s.products_id where p.products_status = '1' and p.products_id = p2c.products_id and pd.products_id = p2c.products_id and pd.language_id = '1' and p2c.categories_id = '21' and p.products_fsk18 <= 1

[TEP STOP]

How can I fix this ???
