Related Products not showing on frontend

[Nilsy]

VM 3.0.10
Joomla 3.4.4
Linux
Pro server etc

After I upgraded from J2.5.28 (if I remember correct, it was the last Joomla 2 versjon), everything is as it should be.
Everything works etc... but not Related Products.

I have the backend field etc, and when I type in the products to relate, it seems to accept it.
But, going frontend, nothing is there.

This may be a missing module field in the template itself. I don't know...
The template is a pro paid template. I am just checking here first, before them...
Anyone else hit this trouble?
Any hints?

Test with Protostar, as most problems like this are template related.

Well... it is working again.
Embarrissing... but I guess I should write the reason...

I was updating stuff and products on the backend... jepp, as always etc.
But in the frontend, I was looking at a subdomain! Not the domain I was working on... 
Sorry...

The only problem now is that these realted products are vertical aligned, rather than horizontal.
But, this is a template problem. So I'll get them to take a look, or perhaps attempt a fix myself.

Thank you Jenkinhill!
