Related categories not showing for products

[maxkomarov]

Hello,

Please help.
Related categories not showing for products. Why?

After calling in productdetails/tmpl/default.php

Code Select Expand

echo shopFunctionsF::renderVmSubLayout('customfields',array('product'=>$this->product,'position'=>'related_categories','class'=> 'product-related-categories'));
I can see in customfields.php what

Code Select Expand

$product->customfieldsSorted[$position] is empty.
Where is a problem?

Of course, products linked to related categories.
Thank you
