I had encountered the same issue, steps to solve it are:

  1. Go to this location: app/code/core/Mage/Sales/etc/config.xml
  2. Make a copy of it in app/code/local: app/code/local/Mage/Sales/etc/config.xml
  3. Next on line number 1221 add msrp:

  4. Next add on line 1230 add:

  5. This should solve your issue. Thank you :)

  • Don't ask me why, but this works. Although make sure to fix it in your own separate module instead of directly editing the core. Commented Oct 6, 2017 at 12:19
