We just upgraded from to and getting a blank page when trying to access the cart or add products to it. This happens for logged in customers only and only when compilation is turned on. No log or PHP errors - just a blank page. We found this but not sure how to properly edit the file. Please help with exact instructions on how and what file to edit.

  • I am having the EXACT same problem. Only for logged in customers and when compilation is On. I just upgraded to as well. I am using the original RWD theme as well. – James Tsai Mar 6 '18 at 19:08

    I just installed a FRESH copy of the Magento community edition on my server. This one with absolutely no added extension. Once I compiled, I am getting the same Blank Page on my cart and checkout. I am surprised how come there is so little people coming up with this bug! – James Tsai Mar 7 '18 at 9:13
  • can confirm the issue with compiling enabled... methinks: if you haven't already, it's time to look at opcache or something similar... – DM8 Mar 8 '18 at 20:59
