With the last bugfix of taajny, mysql might give the error:
"1052 - Column 'products_options_id' in field list is ambiguous".

A simple modification to fix that error:

File to change:
~/catalog/admin/includes/functions/general.php

Around line 928, find:

$options_query = tep_db_query("SELECT products_options_id, products_options_values_id FROM " . TABLE_ORDERS_PRODUCTS_ATTRIBUTES . " LEFT JOIN " . TABLE_PRODUCTS_OPTIONS . " ON products_options_name = products_options LEFT JOIN " . TABLE_PRODUCTS_OPTIONS_VALUES . " ON products_options_values_name = products_options_values WHERE orders_products_id = '" . (int)$order['orders_products_id'] . "'");

CHANGE TO:

$options_query = tep_db_query("SELECT opa.products_options_id, opa.products_options_values_id FROM " . TABLE_ORDERS_PRODUCTS_ATTRIBUTES . " opa LEFT JOIN " . TABLE_PRODUCTS_OPTIONS . " ON products_options_name = products_options LEFT JOIN " . TABLE_PRODUCTS_OPTIONS_VALUES . " ON products_options_values_name = products_options_values WHERE orders_products_id = '" . (int)$order['orders_products_id'] . "'");

That's it.

Only one file, contains the same text at this description above.
