Hello, hope this is the right place to ask for help.
I have installed the contribition, but when I get to installing the boxes module I get the following error:
PHP Fatal error: Call to undefined function tep_get_filter_sql() in D:\Domains\littlecreativedays.co.uk\wwwroot\catalog\includes\classes\specifications.php on line 107
I have checked that the catalog/includes/functions/products_specifications.php exists - and contains the function. Any ideas please?
