Products table empty in admin

Hello,

We’ve taken over a shop with an install of eShop, that’s using the latest version of the plugin, together with WP 3.9.

When looking at eShop > Products, we can’t see any products listed, even though it says “Displaying 1–10 of 107” at the bottom, and we can paginate between batches of 10 – still no products are actually listed.

I’ve tried disabling all plugins, changing to 2014 theme, but still nothing seems to work. I’ve searched online, but haven’t seen any info about this. There is no product data in the source code on the admin Product page table.

In case anyone has had any similar issues, it would be great to hear what could be done to solve this issue.
