Hi,
Thx for your prompt reply and custom code.
I have added the code the related.php and I notice some difference but unfortunately, its not working quite the way my client wants it to. For example they want to show below the single product in the subcategory “aanvoerapparaten” only other products from the same subcategory.Now it looks like this http://rando.divi-test.nl/product/steff-2048/. As you can see other machines of different subcategories are listed as well.
Has it something to do with the permalink structure?
The FTP should work. Have you tried to set it to insecure connection?
Really hope you can help me out again.
Thx for your kind assistance.
Regards,
Johan
