I have OC 3.0.2 default theme and I'm having a problem with the weight estimate popup that should show when I click on shopping cart > calculate shipping costs. It shows perfectly well in my default language (Portuguese) but not in my second language (French). I tried to remplace all French language folders with the Portuguese ones but the problem remained. The automatic weight calculation works for both languages during the checkout process. I haven't found a solution on this forum so far and hope someone will be able to help me.
