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

[sergey]

if you find the fix above does not correct all issues, you need to replace the following sql query in the file includes/modules/meta_tags.php to fix your Zen Cart:

$sql= "select pd.products_name, p.products_model, p.products_price_sorter, p.products_tax_class_id,
p.metatags_title_status, p.metatags_products_name_status, p.metatags_model_status,
p.products_id, p.metatags_price_status, p.metatags_title_tagline_status,
pd.products_description,
mtpd.metatags_title, mtpd.metatags_keywords, mtpd.metatags_description
from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd left join " . TABLE_META_TAGS_PRODUCTS_DESCRIPTION . " mtpd on mtpd.products_id = p.products_id and mtpd.language_id = '" . (int)$_SESSION['languages_id'] . "'
where p.products_id = '" . (int)$_GET['products_id'] . "'
and p.products_id = pd.products_id
and pd.language_id = '" . (int)$_SESSION['languages_id'] . "'";

with:

$sql= "select pd.products_name, p.products_model, p.products_price_sorter, p.products_tax_class_id,
p.metatags_title_status, p.metatags_products_name_status, p.metatags_model_status,
p.products_id, p.metatags_price_status, p.metatags_title_tagline_status,
pd.products_description,
mtpd.metatags_title, mtpd.metatags_keywords, mtpd.metatags_description
from (" . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd) left join " . TABLE_META_TAGS_PRODUCTS_DESCRIPTION . " mtpd on mtpd.products_id = p.products_id and mtpd.language_id = '" . (int)$_SESSION['languages_id'] . "'
where p.products_id = '" . (int)$_GET['products_id'] . "'
and p.products_id = pd.products_id
and pd.language_id = '" . (int)$_SESSION['languages_id'] . "'";
