Hello. I am a new user and i have almost finished my shop. First of all sorry for my poor English because I'm not a native speaker. To make my shop running I need to add the contribution 'quantity price breaks per product'. Every of my products must have separate prices depending on quantity and I can't open my shop without it. After I install the contribution (latest version and I have tried older versions also) my shop doesn't apear. All I'm getting is a blank page with no errors and no text. This happens avery time I'm adding the contributions. I tried to install it different ways like manual step-by-step, using merge software, istalling whole shop again and applying the contribution to stock installation and it just doesn't work. If you know what might be the problem please let me know or are there other modules like this one that I could try? Just to remind: every of my product must have separate prices depending on quantities and these cannot be global discounts. You have done great work by creating these contributions and all of the stuff. Please help just one more newbie :)
