Hi, please, somebody help me with products attachments. After upgrading Prestashop to 1.4.3 all products attachments after downloading can not be opened. I used only .pdf attached to all products, such as data-sheets and brochures. When I visit product page and download datasheet .pdf, adobe acrobat says that : There was an error opening this document. The file is damaged and could not be repaired. There was an error opening this document. The root object is missing or invalid. The confusing thing is that I have a copy of my website in my local computer with MAMP. All attachments in my computer are working fine, but on the website not. Please, any suggestions !!!
