I have made changes in the language, but unfortunately "prices", "Categories" and "MANUFACTURERS" I could not translate. I have found that in default_product_filter.php in line 31 that adding
<? Php echo JText :: _ ('VM_PRICES'); ?> And eliminating
<? Php echo ucwords ($ key); ?> In "ft-current-group" and then filling in the language of the module., Make the translation but takes the same for categories and manufacturers have the same header.
Would need to translate what indicated in the picture PRICES , CATEGORIES AND MANUFACTURERS. Thank you
