Hi everyone I'm hoping that someone here can offer me some assistance. I have oscommerce 2.2ms2 installed ( have posted in their forums and have been unsuccessful in getting a solution to my problem) I am getting the following error message when I click on the subcategory links of products offered aswell as on the manufactures links. The url where this can be viewed is [a href=\"http://www.webwolf.co.za/catalog\" target=\"_blank\"]http://www.webwolf.co.za/catalog[/a] Everything else works fine. [code]Fatal error: Cannot pass parameter 3 by reference in C:\wamp\www\catalog\includes\modules\product_listing.php on line 13[/code] this is what is on line 13 & 14 in the relevant file [code]$listing_split = new splitPageResults($listing_sql, MAX_DISPLAY_SEARCH_RESULTS, 'p.products_id'); if ( ($listing_split->number_of_rows > 0) && ( (PREV_NEXT_BAR_LOCATION == '1') || (PREV_NEXT_BAR_LOCATION == '3') ) ) [/code] I would be most grateful for any help. I have tried going thrught the references at php.net and am unable to understand what they mean. I'm still in the process of learning.
