After upgrade to hikashop2.5.0,I was scared by the only one column style of 2.5.0.
I doubt if I already installed successfully.I tried three times and it was the same.

Now I found on problem that I can not add related products when editing.I couldn't select beause all products displayed null,please see it in attachment.

Anything wrong?
Please help ,thank you very much.

We already fixed that issue, so you'll just have to download the last Hikashop version through our website, install it and test it again.

ok, SOLVED.
