Journal2 is still one of the most popular OpenCart themes and MultiMerch is one of the most popular multi vendor extensions for OpenCart – and we intend to keep it this way.
Therefore, we've just updated our Journal2 integration pack for MultiMerch 8.x and created a definitive guide for installing OpenCart with MultiMerch & Journal2.
The latest version of the Journal2 integration pack includes over 50 styling fixes for various MultiMerch templates as well as a fix for Journal's Quick Checkout system. It will also get updated on a regular basis.
