I am using ver 4.7.4
I am facing 2 problems
1.I am trying to make minor modifications to invoice.tpl mostly css
cc and ctpl after mods but NO changes affect, I also tried to empty the files to produce an error BUT nothing !
2.I can see the barcode at admin->view->order and at cusstomer->my orders BUT not inside an invoice
I cannot understand what is causing these problems
