Hi David,
Since a few weeks we are having the same problems with the related products.
We are using the divi theme and until a few weeks ago it worked great.
Within the plugin we have choosen to pick the related products manually. Feature Relate Manually is active.
This to force the right related products to the main-product.
This feature wasn’t decribed in the explanation of the booster, but it worked well for some weeks ago.
The related products of the main-product are still in the productdefinition, but the won’t be shown anymore at the frontside of the website.
It now shows random products only.
If I change the number of columns or products in the plugin, the changes are shown in the frontside of the website.
So these features are working well.
Please advice us what to do, to show the manually choosen related products again.
