nrelate not appearing

Hi guys,

I have installed nrelate but it is simply not appearing. Any idea why this may be?

I am not exactly a website whizz so if I need to change something can you try and make it sound as simple as possible.

Many thanks!

By the way, my website is: https://www.first4lcfc.co.uk/

And the nrelate suggestions should be beneath my posts, such as this one:
