Not all files are customizable⦠but this one looks like it is, the includes for it seem to be:
modules/AOS_Products_Quotes/Line_Items.php:35: $html .= '<script src="modules/AOS_Products_Quotes/line_items.js"></script>';
modules/AOS_Products_Quotes/Line_Items.php:36: if (file_exists('custom/modules/AOS_Products_Quotes/line_items.js')) {
modules/AOS_Products_Quotes/Line_Items.php:37: $html .= '<script src="custom/modules/AOS_Products_Quotes/line_items.js"></script>';
So it seems to be looking in custom. Did you keep the correct uppercase characters? Itās Line_Items.php but line_items.js
