Hello, I also had this problem and no solution from the above worked for me. My setup: Version 1.5.6.0, Greek language, English language disabled, my-theme a modified default theme In my-theme folder themes/my-theme/modules/sendtoafriend/mails there was only a folder "el" for the Greek languageNo English folder. This seemed to be the problem. I coppied the en folder from modules/sendtoafriend/mails to themes/my-theme/modules/sendtoafriend/mails Uninstalled and reinstalled the module sendtoafriend And miracle! Everything works fine.

Great solution! Thanks

Partialy solved Case 3 Case 3: A simplified method would be to just multiply the weight with the price of the 1 and only Weight Range P = the price from the first and only Weight Range W = the weight of the order Shipping cost = W*P In Carrier.php line 250-253 I added * $total_weight. So now the Weight Range price is considered to be the per kg cost and not a fixed price. if (!isset($result['price'])) self::$price_by_weight[$cache_key] = $this->getMaxDeliveryPriceByWeight($id_zone) * $total_weight;//added * $total_weight; else self::$price_by_weight[$cache_key] = $result['price'] * $total_weight;//added * $total_weight; It seems to be working. And even better it calculates the price of the correct Weight Range, so we can have as many Weight Ranges as we wish. I am new to PHP so I am not sure that everything is OK. Also I don't know how to make Case 2 Any help?

Hello everyone, I would appreciate any response to my question. I see that there are similar posts, so other people might have the same problem Unless I misunderstood, the shipping cost in Weight Range is fixed for all the range. Case 1: Weight Range: 10-15 kg - Price: 2 Euro. This means that the shipping cost will be 2 Euros for any quantity between 10kg and 15kg. I suppose that the code for the calculation of the shipping cost is something like: “Lookup for the shipping cost for this weight range” Case 2: I don’t know how it works in the other countries, but our carriers in Greece would charge: - a fixed rate for the first weight range (eg: 0 - 2 kg - 6 Euros) and - per kg for the rest of the quantity (eg: 2 - 50kg, 1,5 Euro per kg). So a pack weighting 10kg would have a shipping cost: 6 + (10-2)*1,5 = 18 Euro In this case the code for the calculation of the shipping cost would be something like this: P1 = the price from the first Weight Range W = the weight of the order W1 = the max weight from the first Weight Range W2 = Subtract W1 from W : (W-W1) P2 = the price for the W2 Weight Range Shipping cost = P1+ W2*P2 Case 3: A simplified method would be to just multiply the weight with the price of the 1 and only Weight Range P = the price from the first and only Weight Range W = the weight of the order Shipping cost = W*P My question is: Can I modify the code so that the shipping cost is calculated according to Case 2 or Case 3? And if so, how and where is this code?

Hi, I just downloaded and istalled Prestashop after testing it online. It was really simple to install following the instructions. But when I try to make any change from the admin section I get an error: Bad Gateway Web server received an invalid response while acting as a gateway or proxy server. Still the changes are recorded to the database. Could anyone advise me how to fix the problem?
